Great Power

"Yes, your game is a good game. You sold half a million copies in three months. This is the fastest game ever to reach this sales figure. It brings Fairchild Entertainment nearly 20 million in revenue. , But it still cannot save Fairchild’s crisis. After all, entertainment is not Fairchild’s main business, and semiconductors are its life--"

The reporter who spoke clearly knows Fairchild Entertainment better, but these are of little significance to Zheng Jianguo. He does not know what semiconductors are, nor does he know that Fairchild, a company that represents the history of Silicon Valley, belongs to the electronic technology industry. "West Point Military Academy", not to mention the importance of semiconductors in the future.

On the contrary, Zheng Jianguo is very clear about these. He even knows that Intel and AMD, which are unknown at this time, will become global giants in the future, and the founders of these two companies were both founded by Fairchild Semiconductor. In the next year, semiconductors will enter thousands of households and turn the earth into a village.

But because of this, Zheng Jianguo dare not come into contact with this company too much. The boss of Wang An Computer is an authentic American. He has studied and worked in the United States forty years and started an office company. All the connections were broken, as if those no longer existed when he announced it, but even this did not live until thirty years later——

Zheng Jianguo doesn’t know how the computer company is cold, but he knows that what he can do at present is to make a fortune with the seemingly "lucky" chance to make money. By the way, he can make a deduction on his forehead that is enviable. Luck-silver is so gold and so is gold.

The former is Van Dailin’s discovery of the Harland family’s conspiracy, and the latter is a hedge investment that ordinary investors will choose. Of course, this is based on the fact that the price of gold will not fall into a negative number and its own value. The purpose is that Zheng Jianguo vaguely remembers the two countries at the end of the year. When the war broke out, oil rose, and gold rose.

And this is the best that Zheng Jianguo can do. The sixteen-year-old young man made a lot of money by investing in a halo of learning dominance. Although it is a little beyond people’s imagination, it is still within the normal range. However, if he does this For a while to mix semiconductors, which are the lifeblood of industry, this risk is countless times greater than after the success of the research he is doing: "Unfortunately, I haven’t been in contact with solid-state physics for long. The semester arranged by my basic physics teacher The homework is to do a physics experiment, can you believe it? Just take a mirror and a basin of water to do a refraction experiment—"

"Isn't that a rainbow experiment?"

Some reporters said that Zheng Jianguo tilted his head and raised his brows as if you had answered correctly: "Yes, the rainbow experiment is also fine, maybe Professor Thomas thinks that those of us who go to elective courses are just to relax—— "

"Zheng, what experiment are you going to do?"

A reporter put away his notebook and asked curiously, then looked at the reporter who had mentioned the rainbow experiment and smiled: "Are you also doing a fun experiment for junior or elementary school students?"

"No, I plan to grind graphite—"

Zheng Jianguo raised his eyebrows and shook his head and said, the reporters also laughed happily: "It's an experiment too--"

"Is it the graphite of the pencil?"

"Graphite haha—"

The reporters dispersed in twos and threes. Zheng Jianguo carried the bag into the teaching center, and found the secretary of the department, Belinda, who had said about the morning, and saw that she was shocked and said: "You, how do you need the college to help you? ?"

"I want to live in the college, I can pay."

Zheng Jianguo said, Belinda nodded immediately: "This is no problem, I can tell the management office, if it costs, I will tell you, how did you study in Massachusetts? Are you sure? Get a B+?"

"There needs to be an experiment. I believe that B+ is okay. I will ask you about the residence, Belinda."

Near the summer vacation, most of the courses at the medical school are mainly review. Although Zheng Jianguo's identity is a little transcendent, the conditions and requirements given by the school are also equal. You can choose the courses you want to take but you need to pass the selected courses. Assessment.

Fortunately, after Zheng Jianguo entered Harvard Medical School, the difficulty he faced was not the assimilation of the professor's knowledge like other medical students, but the matching of the Chinese in his memory and the Chinese English he had learned, and it was easy to pass for more than half a year.

Of course, in Zheng Jianguo’s view, the main reason why he did not feel the pressure to study at this time is that the reform of medical equipment based on the development of computer technology in his memory has not yet arrived, leaving aside the medical human knowledge that accounts for half of the study. , The others are also basic medical courses that are memorized by heart.

In view of the uncertainty that the things in his memory have not yet appeared, Zheng Jianguo mostly listened to and watched less when he was studying. In addition, he was still carrying a video camera, so he did not hand in much after the course of more than a month. Friends, I don’t know as many people as I know in elective courses at MIT.

After reporting the move, Zheng Jianguo did not forget the bad words of the two policemen. Fortunately, the place where he was going to move was the school, and the geographical location did not leave the bounds of the greater Boston city, which is far from MIT. The college is only a 20-minute drive away——

With the car window closed, he crossed the Harvard Bridge on the Charles River with vigilant eyes. Zheng Jianguo also entered the MIT site. He found the address written in his pocket and touched it to Teaching Building No. 36 before he saw himself. His test partner was looking out at the door, and when he saw his car appeared, he quickly approached the front of the car: "Zheng, why did you come? Our laboratory was almost taken over by someone—"

The speaker was a white tooth, a classmate whom Zheng Jianguo met in the elective course of basic physics, Brady Binns of Harvard Law School, and he was the only alumnus in the entire Harvard University who reported basic physics, so the course ended. Become a teammate in the assessment group test: "If Celia hadn't reported your name, it would have been taken."

Celia Keynes is a MIT chemistry major, a genius girl who is only one year older than Zheng Jianguo. As for the elective course of basic physics, she belongs to the only normal person in the trio.

After all, compared with the law school and medical school of the two, the chemistry major is closer than the basic physics, but when Zheng Jianguo found a good place to park and arrived at the door of the building, Brady spoke again: "Celia took it. Her sister came over and said that she was a PhD in solid state physics, considering that we involved a deeper knowledge of the experiment, and used it to help us conduct the experiment—"

"What's deep, let's just observe it?"

Zheng Jianguo said in his heart as if he accidentally said, then he found Brady's face full of question marks and said: "Observation itself is an experiment. Is it possible that you have to get results?"

"Huh? You are right--"

After Brady swallowed a fly and blinked his big eyes, he quickly caught up with Zheng Jianguo's footsteps: "Of course it is good to have results, right?"

"You don't care what kind of experiment we are doing, the results will be great."

Zheng Jianguo shrugged to the elevator entrance, and Brady next to him once again showed a small face that swallowed a fly, and quickly nodded: "Yes, too, if we find out, I feel that I can switch careers—"

"You, a law school, want to transfer to engineering school?"

Pretending to ask indifferently, Zheng Jianguo stepped into the elevator that had already explored the terrain. After entering the elevator, Brady pressed the fifth floor button, looked at the number of the beating floor, and said, "I mean if there is any discovery. If you don’t, it’s okay if you can’t transfer. It’s a big deal to study two majors at the same time—"

"——"

In his heart, he paid the highest tribute to this white tooth brother. Zheng Jianguo remembered that he is now at MIT, the highest institution on the apex of the pyramid, the university that all high school students in the world dream of. Of course he is facing this The boastful White Fang was also not ashamed: "You didn't plan to take a medical school after graduation—"

"Don't be kidding--"

Brady glanced at Zheng Jianguo in shock, then quickly shook his head and said, "Then I would rather take the three major degrees—"

"Ha ha."

When Zheng Jianguo was smiling, the elevator door opened, and Brady stepped out first, just in time to see Celia standing in the corridor, tall and thin wearing a sweater, with thick eyebrows and big eyes that look more like a boy than a girl: Zheng, you are here at last, and we should look for you if we don't come again."

"Something happened to the residence, but it's okay now, shall we start now?"

Zheng Jianguo’s camera and battery pack were thrown into the car. He hadn’t said anything except the notebook at this moment. The white glass door opened behind Celia, and an obviously mature girl appeared next to her: “Here is coming. Let's start when you come? You start with graphite grinding?"

"Then start by grinding graphite—"

Zheng Jianguo looked at the girl and then looked at Celia. The latter said, "This is Ulrika sent by the teacher after learning that we are going to do the graphite experiment. She is Professor Thomas’ Ph.D. This year’s graduation thesis is In terms of graphite—"

"The Chemical Reduction and Separation of Graphite Oxide by Hydrazine Hydrate and Divalent Iron Salt." This is my graduation thesis this year and has passed the defense."

Ulrika’s eyes were full of curiosity on the high bridge of her nose. She was not concerned about the cross-border exploration of these three curious babies: "Since 1840, the German scientist Schafhaeutl believed that the graphite interlayer relies on the weaker van der Waals. Since the graphite interlayer can insert small molecules of acid or alkali metal to prepare graphite interlayer composites, in the past more than a century, countless scientists have only obtained a thin layer of graphite with a thickness of 46 nanometers. I don’t know how many parts of a hair is 1 nanometer—"

"One in 60,000!"

Brady, who was next to him, raised his hand and said at some point, and then found that Zheng Jianguo and Celia were looking at themselves, shrugged and said: "What, did I say wrong?"

"No, you are right, it is indeed one in 60,000."

Ulrika raised her eyebrows, then glanced at the entrance next to her and said, "Okay, let's change our clothes and enter the laboratory. Brady, will you come to grind the graphite? You should grind it as thinly as possible. ——"

"OK, no problem, leave it to me—"

Brady looked at Ulrika’s face with excitement, but Zheng Jianguo, including Zheng Jianguo, could see his eyes move down a lot on Ulrika’s face, and then turned around and entered the dressing room and began to wear clean clothes. After the four entered separately, Ulrika took out a thin piece of graphite the size of a thumb from the white material cabinet: "There is a grinder on the table. I will teach them both to adjust the microscope and spectrometer. You are ready to say— —"

"Unexpectedly, I have searched for more than 140 years and have not found it, but I remember there is a theorem or some proof that two-dimensional materials cannot appear in nature, right?"

After taking the thin graphite and feeling its thickness with fingers with finger cots, Brady's eyes swept over the thickness of a few sheets of paper, and Ulrika nodded and said in surprise. : "Have you done your homework ahead of time? What you describe is the Mermin-Wagner theorem that can be proved based on statistical physics. Classical physics believes that crystals are composed of perfectly ordered particles with a continuous symmetrical atomic structure.

But the Mermin-Wagner theorem in 1966 broke this view: In one-dimensional and two-dimensional atomic structures (such as atomic chains or atomic films), it is impossible to have perfectly arranged particles for a long time.

So some scientists think that it is impossible for two-dimensional materials to appear in the natural world at room temperature, but the curiosity of scientists can't stop. Don't you want to see the true face of one layer of graphite or several layers?"

"Well, I want to see it, but I'm here to experiment—"

Brady turned to look at the graphite sheet in his hand and shook his head. He said that when he wanted to reach out and turn on the grinder, Ulrika's voice came from behind: "Put on goggles and gloves. And masks, you don’t want to inhale molecular-grade graphite into your lungs. Believe me, you definitely don’t want to see patients with advanced pneumoconiosis. I only warn you once. No matter what grinder is turned on, remember to protect yourself and protect yourself. ."

"Ok, yes, I will put it on right away."

Brady tilted his head without looking back, picked up the protective goggles and mask next to him, and then looked around at the stool under the sanding machine table. He immediately pulled out and sat in front of him and turned on the bright light. Looking at the lamp, I have done all the preparations I can do, and I turned on the switch depressed in my heart, and pressed the thin graphite sheet in his hand on the high-speed rotating grinder.

It’s just that the graphite sheet that Brady expected seems very hard and hard. It will be pulled back to see if it is worn out. There are only slight scratches on it. Then I turned my head and looked at the three behind the microscope. He turned his head and pressed the graphite sheet hard on the sanding machine: "Hey——"

"After Brady is finished, we can use this 300-nanometer thermally oxidized silicon wafer as a substrate for observation."

Ulrika followed Zheng Jianguo’s gaze and looked at Brady behind her. She said, remembering something, and she said, “The graphite dust for polishing should be taped off so that you can see the surface to be polished. how is it like--"

"Oh, good!"

Brady’s voice came, and Ulrika looked back at Zheng Jianguo and Celia and said: “Of course, before this, our preparations are to put these substrates in the ultrasound of acetone and absolute ethanol. Wash in the machine for twenty minutes to prevent the surface from being contaminated--"
