Chapter 150 The Nobel Prize
National Library (Note 1)

"How is it? Did you find anything?" Qu Yanqiu walked over.

"No."

Chen Quan shook his head. "Indeed, as Section Chief Wang said, there is no mature MOCVD product on the market. 'His' design is indeed the first in the world."

After inspecting Fengtian, Chen Quan and others ran to the capital without stopping.There are also several equipment factories in Beijing that need to be inspected.

Chen Quan won unanimous admiration in Fengtian Science and Technology, and that MOCVD design drawing became another proof of his inborn knowledge.

For this public performance, Chen Quan finally made up his mind after a fierce ideological struggle.Because he has no other choice.

Leaving the environment of the scientific instrument, Chen Quan was not sure at all that he could memorize all the information contained in such a large drawing and reproduce it as it was.

Of course, Chen Quan and Qu Yanqiu gave some explanations to the blueprint, such as being well-informed, drawing ladles from gourds, thinking day by day and dreaming at night, etc.

Regardless of whether others believed it or not, Chen Quan and Qu Yanqiu themselves believed it anyway.

Despite what they said, Chen Quan and Qu Yanqiu went straight to the library as soon as they arrived in the capital.

The two had searched for blue-light LEDs for a period of time, but the Ice Industry University did not focus on the semiconductor industry, and the relevant information was incomplete.

Regarding MOCVD, the two of them didn't even check it.Before going to Fengtian this time, Chen Quan didn't even know what MOCVD stood for.All relevant information is activated after arriving at the instrument.

Don't look at Chen Quan's tongue-in-cheek battle with the Confucians, he looks confident, but he is actually very guilty.His legs shook from head to tail for 4 hours.

Although Chen Quan was very guilty, his big heart had already been exercised.

The situation faced during the Lübeck MEMS conference was far more dangerous than that of Fengtian.So apart from Qu Yanqiu, who was familiar with him, who had noticed it, most of the others believed that he was the aftereffect of dizziness in the morning.

Chen Quan searched in the National Library all morning, and finally heaved a sigh of relief.

Not long after its completion, the National Library, which was rated as one of the top ten buildings in Beijing in the 80s, far exceeds the old library of the University of Technology in terms of area and total number of books.

From the information found, it can already be proved that "he" is still credible and reliable as before.

"Tell me, what kind of person is 'he'?" Qu Yanqiu asked. "According to the clues in your memory, he first started MEMS and blue LEDs at the University of Technology. In the end, within two years, he went to West Germany and became an ordinary system engineer. Neither the time nor the status was right! "

Anyone with a normal mind would be suspicious of Chen Quan's performance in Fengtian, because it was too contrary to common sense.But seeing is believing, no matter how unreasonable something has happened, everyone can only accept it.

Instead, Chen Quan and Qu Yanqiu gradually became suspicious.

"Oh? What did you find out?"

"Look!"

Qu Yanqiu spread some materials on the table.

"I can understand the MEMS project. After all, MEMS is mainly based on creativity. No one has paid attention to MEMS technology before. In an emerging field, it is easy to catch up from behind.

But blue LEDs are different.Since LED was officially commercialized, many researchers, institutions, and companies have invested energy and money in blue LED.Almost as long as it is a technical route that people can think of, it has been explored countless times.

In this kind of project, it is impossible to win only by creativity. "

"Yeah. I feel the same way."

Chen Quan nodded. "If the MOCVD design drawing is really his own design, then he has been immersed in the field of equipment design for at least ten years."

"Ten years? I'm afraid you still say less!"

Since it was in the library, Qu Yanqiu tried to keep the volume down as much as possible. "You didn't listen to Director Liu's discussion?
The completeness and perfection of this MOCVD is really too high!In addition to equipment design and mechanical design, MOCVD is different from ordinary equipment. To design a mature product, designers need to fully grasp many fields from machinery, electronics, materials, pneumatics, transmission, chemistry, to high-temperature containers.

How can this be done within ten years?
Not to mention, there are so many innovative points! "

"Yes. Indeed."

Facing the facts, Chen Quan could only nod and admit.

As a scientific and technical personnel, the development of new products and new technologies is a normal operation.But for a project, it is too hard to design such a complex large-scale equipment.

"Actually, when I was in West Germany, I felt a little strange. From the semiconductor field, I jumped to software programming, which is completely different. There is almost no overlap between the two."

"That's right, and the timing is completely wrong. After he succeeded in MEMS, he immediately started the LED project. According to the technical level contained in MOCVD, even if he works full-time, he still needs to wait until after 2005 to achieve something. And Judging from the information you gave, he had already gone to work in West Germany at that time." Qu Yanqiu continued in a low voice.

"yes."

Chen Quan unconsciously agreed.

In the past, the focus of the two people was just 'them', and they studied who 'they' were and what their purpose was.Unexpectedly, "he" actually hides so many secrets.

"In fact, I have been observing Cheng Xing all the time, but no matter how I observe, I can't see anything special about him. If he really has such ability, your perfect match will be nothing to compare with. Just admit defeat."

"Actually, not necessarily." Chen Quan didn't think so.

"why?"

"Do you think I'm a real genius?" Chen Quan asked, shaking his head in response. "I met an adventure, will he also have an adventure?"

"Forget it, don't think about it. The more you think about it, the more unreasonable it becomes."

Qu Yanqiu quickly changed the subject. "I also found something that you might be interested in."

"what?"

"Nobel Prize!" If it wasn't for the library, Qu Yanqiu would have screamed. "Blue LED, it is possible to win the Nobel Prize!"

"real or fake?"

Chen Quan stood up in shock.

"Of course."

Qu Yanqiu pointed to the magazine and translated word by word. "Cold light source, the luminous efficiency of LED, completely crushes the traditional heat light source. Once it has a breakthrough in the last short board, blue LED, the cold light source will completely replace the traditional incandescent lamp and complete the technology update. From this point of view, blue LED technology is fully qualified to be nominated for the Nobel Prize."

"Wow!"

Chen Quan took the magazine in surprise and read it line by line.

Finding the right project for the perfect competition has always been a heart disease for the two of them.With no hope in sight, the two turned their attention to the industrial chain.

"By the way, after this MOCVD machine arrives, the blue LED can be completed."

"It's not that easy."

Chen Quan shook his head.

"What?" Qu Yanqiu was extremely disappointed.

"Look here." Chen Quan dug out a journal from 1985. "The Japanese, Hiroshi Amano proposed a two-step method. Through the method of AIN buffer layer, they also found a way to prepare GaN.

Hiroshi Amano’s approach is to grow a layer of AlN buffer layer under low temperature conditions. Since the buffer layer releases the mismatch stress between GaN and sapphire, the quality of the GaN crystal prepared by increasing the temperature is significantly improved. "

"so?"

"That is to say, even with this MOCVD, we are only catching up with Hiroshi Amano's achievements five years ago."

"But didn't you say that with this equipment, blue LEDs can be made?"

"Yes. I did say that, but this does not mean that only MOCVD is the key device for blue LEDs, and the preparation of the GaN layer is the only key step."

"What about the other steps?"

"It's written in this review." Chen Quan found another journal.

The biggest crux of GaN light-emitting diodes is that P-type doping has always encountered difficulties.The p-type dopant that is often used in GaN is Zn or Mg, but after doping with impurities, GaN often still exhibits high resistance characteristics, which means that the p-type dopant is not activated and has no effect.

In addition to the problem of P-type doping failure, there are some other miscellaneous problems.

The GaN route is the longest research route for human beings to study blue LEDs, so Chen Quan found a bunch of literature.

"Are you sure that 'he' has the answers to these questions?" Seeing that there are still so many problems to be solved, Qu Yanqiu felt that he fell from heaven to hell all at once.

"Yes. He must have solved all related problems."

Chen Quan's reply this time made Qu Yanqiu rekindle hope.

"How did he solve it?"

"Do you remember, I said at the time that this blue LED is not the same as MEMS, it's just a very vague memory."

"Yes, I still remember."

"The reason these memories are very vague is because blue LEDs were not made in a microelectronics lab."

"Oh? Not in the microelectronics laboratory, but where?" Qu Yanqiu didn't care. "Wherever it is, let's go."

"No! We have no way to go to that lab, because that lab doesn't exist."

"Doesn't exist? What does it mean to not exist?"

"Literally. The lab where 'his' developed blue LEDs doesn't exist in our world."

"You didn't mean to tease me!"

Qu Yanqiu's two big eyes flickered. "The laboratory doesn't even exist, how do you get those memories back?"
