Rebirth of Northland Technology

Testing major, Greek Director's Office

"Director Xi!"

Cheng Yongxing greeted them one by one as soon as they entered the house, but not everyone knew him.Several strangers sat in the room.

"Come on, let me introduce you! This is Director Zhang Qiang of the Department of Materials Science, and this is Teacher Liu Hongtao. This is Professor Sun."

As a disciple, Director Xi introduced several guests one by one.

"This is Xiao Cheng, Cheng Yongxing, I don't think you need to introduce it, you should know each other."

"Director Zhang, Professor Sun, Teacher Liu, early!"

Cheng Yongxing nodded again to several guests.

"But, Director Xi, what did you call me here this time? How about I wait a while?"

Cheng Yongxing rushed over after receiving the call.But looking at the guests in this room, I was at a loss.

—————————

"Look at this thing, is it what you want!"

Director Xi smoothly pushed a few thick glass bottles on the table, filled with yellow powder.

"Is it "Yttrium Aluminum Garnet Phosphor"? There will be results so soon?"

Cheng Yongxing has been looking for this material.He was not familiar with other majors, so he entrusted this matter to several teachers.I didn't expect the result to be so soon.

"This is something we made specially for you. The kind of thing you want is not available in the laboratory. According to the formula you gave, several of us researched and made a few batches of samples. use!"

A young teacher Liu volunteered to explain it next to him.

"Thanks a lot then!"

Cheng Yongxing quickly stood up and saluted.These humble phosphors are important materials for white LEDs.I didn't expect it to be so easy.

"Could you take the liberty to ask? Is there any use you want these samples?"

"These materials are important raw materials for my next experiment."

Cheng Yongxing can only be vague.

"If we didn't guess wrong, these are also related to the project you are working on now!"

"Yes!"

There are still many smart people in this world.

—————————

"Xiaocheng, I read your papers. From these papers, I really feel admired. In the past few months, you have actually made so many things! No wonder it caused such a sensation. ."

The flattery of intellectuals is more beautiful than ordinary people.These days, Cheng Yongxing has been photographed so much by everyone and almost fainted.But this time the flattery was fresh and refined and made him very comfortable.

"But if you want to continue doing it, you might not be able to do it!"

Hey, how has this style of painting changed?What does it mean?In the past two days, Cheng Yongxing has heard all kinds of compliments. This is the first time someone has slapped him in the face.

But he didn't instinctively refute it, because he did feel a little lacking in skills.In fact, Cheng Yongxing can no longer take into account the two paths of company operation and scientific research.And in the company, there are many branches of work such as process and equipment.

In history, Nakamura has come to this step, and the final step of these product optimization and mass production was completed by the company by others.Later in the process of optimizing LED brightness, there are several key nodes, but the person who completes these nodes is his assistant.

—————————

"If I am not mistaken, you are going to go on the LED road!"

Photoelectric research, this leather bag company has recently become a hot spot in the school.Many people are watching with their eyes wide open, hoping to see a miracle or tragedy.

"But the production of LEDs is different from scientific research. The brightness needs to be optimized, the lifespan needs to be prolonged, and the cost needs to be reduced. In addition, the LED production chain is so long. Types, proportions of doping, subsequent cutting, packaging, these scientific research and production, are you ready to cover the world alone?"

No one in the room speaks anymore, just listening to Director Zhang's single voice reverberating continuously.

"For these jobs, others can't help you, but we can. Our Department of Materials can."

The material department is very strong and will be upgraded to a college in a few years.

The major of semiconductor materials under the Department of Materials is actually the counterpart of LED.And not only that, after the semiconductor materials major was removed, they established a packaging major, which is also one of the popular majors in the University of Technology.In addition to these two majors directly named as semiconductors, there is also a major related to semiconductors, which is optical information science.Photovoltaic power generation in the ascendant of later generations is the domain of this profession.

So in a sense, in the field of semiconductors, the most powerful of the University of Technology is not the electronics department, but the materials department!

In addition to semiconductor-related majors, other materials majors are also urgently needed by Cheng Yongxing.The phosphor placed on the table is one of the evidence.

—————————

"Well, how can you help me?"

When Cheng Yongxing was first accused, he still felt a little uncomfortable.Most people always have this kind of unconvinced psychology.Especially the public opinion during this period of time made him feel a little airy.

Loyalty against ears.He is not the kind of real young man, in front of the facts, he quickly changed his mentality.

"In fact, we have some guesses about the purpose of this bottle of phosphor. We can cooperate in this model.

Your advantage is flexible thinking, focusing on hotspots of science and technology, and the market is accurate, but the disadvantage is insufficient resources.On our side, we have resources, but we lack the sensitivity to the industry and it is difficult to produce results.So we can join forces."

Director Zhang provided a brand new cooperation plan.In schools, there has been constant emphasis on the transformation of scientific and technological achievements, but the effect has always been poor.The main reason here is that scientific research is out of touch with market demand.

How to transform scientific and technological achievements without a market?Asking a group of professors and students to find a market for their own achievements behind closed doors is more difficult than ever.

However, the emergence of optoelectronic research has provided a new possibility for the Department of Materials, that is, market guidance.

—————————

"And we can do more. Just like this blue LED paper, you use two new methods, a double heterojunction structure and a light-emitting center, to increase the brightness of the LED.

But your papers are all about results, not theory.You have not explained why these two methods increase the brightness."

This is Professor Sun next to him speaking.They also came prepared this time.For this ultimate dialogue, he actually read Cheng Yongxing's thesis thoroughly.

"If you look at it only from the perspective of the paper, your paper will fail at all. Because it is just a description, describing what you have done, and the principles in between are not mentioned. If I were a reviewer of the journal, It will kill you directly!"

Professor Sun’s intellectuals have a temper, and they are very rude.

—————————

"Xiaocheng, don't mind you either. Old Sun has this temper. He is like everyone else."

Director Zhang hurried out to make a round.This young man is now in full swing, and everyone is here to discuss cooperation, not to fight.

"I'm fine, I'm actually worried about this matter."

This paper by Cheng Yongxing is very similar to the paper by Heroes Nakamura in history.They only describe the process without clearing the cause and effect.

This leads to a strange result, that is, although the paper is famous, its citation factor is extremely low.Because it has no reference value at all.

All members of the LED team, including Cheng Yongxing, drove the ducks to the shelves, knowing the results but not the principle.However, it is also very difficult for these students to understand the principle.

Because it even involves some professional courses and theories, such as quantum mechanics and semiconductor physics, that are only involved in senior or even graduate level.These courses involve a lot of formula calculations, it is not so easy to learn well.

These courses have never been exposed to Cheng Yongxing's past and present.At this stage, it is obviously too difficult for the junior students, including him, to disprove the principles behind these results.
