Military Industry of Great Powers: Build the Strongest Flanker

"Director Gao, if you don't think of a way, there won't be anything left to eat next month!"

Director Wang complained on the side, and Director Gao paced back and forth in the office.

If the tasks cannot be completed, life cannot go on.

"Director Gao, if you don't keep your focus, just cut off some projects if they need to be cut!"

“Can you tell which items are important and which are not?”

"..."

I wanted to make some extra money selling ice cream in the summer. 14 All the mature air compressor technology has been studied by experts in the institute. It is not difficult to build several cold storages.

It’s a pity that there is no market for this!

Some people proposed to set up a breeding farm, and others proposed to set up a garment factory. They could also use the women in the family area.

But once the initial investment is taken into account... there is nothing to follow.

…

At this time, Zhao Guoqing returned to his dormitory and took out a manuscript from the drawer of his desk. This was a feasibility research report on gallium nitride semiconductors.

What's the point of talking nonsense to Dean Gao? If it leaves a frivolous impression on Dean Gao, things will be difficult to handle.

Engineering students have nothing to say. They need to present facts, reason, and use data to speak.

On the way to Dean Gao's office, Zhao Guoqing thought about it and decided to go back to Engineer Bi's office first.

Since he was asked to join the third group by Chief Engineer Bi, it was equivalent to him being a soldier of Chief Engineer Bi. If anything happened, he had to discuss it with Chief Engineer Bi first.

"We can't do this next time. The way we work in the United States in my memory is different from that in China!"

In the United States, if you have a good idea, you can discuss it directly with the BOSS. As long as you do not affect the project work, the project team leader will not have any objections.

But in China, well... it's called respecting superiors.

"Teacher Bi!"

"Hey, National Day is coming so soon. Have you met Director Gao?"

Zhao Guoqing shook his head and said, "Not yet. I suddenly thought of something. Let me report it to you first!"

"Oh!" Mr. Bi smiled and said, "What's the matter? It's so urgent?"

Zhao Guoqing handed the materials in his hand to Chief Engineer Bi and said, "I have written a piece of material, please correct it!"

General Engineer Bi frowned slightly. In fact, he and Zhao Guoqing had just started contacting each other today. He knew that this young man had great attainments in radios and semiconductors, and that set of design ideas impressed him deeply. It was simply a genius idea. .

As for his personality, he seems to be a bit radical and has clear views on the route of electron tubes and transistors.

It would be understandable if an industry leader suggested that the future is dominated by semiconductors.

It was so unexpected for such a young man to say this.

“Has he ever completed even a single project?”

Even he himself felt that the potential of electronic tubes still had great potential.

The transistor is an almost completely unfamiliar field.

No investigation, no right to speak.

Why does this young man propose that transistors are the future?

He may not know yet, in terms of reliability, have the people from the 107 Institute already tried it?

There weren't that many engineering people in the city, so I was unhappy, and it immediately showed on my face.

He opened the file bag, thinking that if it was unreliable, he would have to give the young man in front of him a good lesson.

This person's talents and abilities are outstanding. Perhaps it is because of this that he floats and cannot keep his feet on the ground.

It has to be straightened out properly. It would be a pity if it goes astray.

"National Day, I'm still more optimistic about you, so I'll tell you, young people, it's right to be aggressive, but no matter what, you must be realistic..."

"..."

Zhao Guoqing scratched his hair and said this. In fact, coupled with forty years of memory, Zhao Guoqing does not regard himself as a young man at all.

In other words, it can be said that his mental age is over sixty, and he is completely an old monster.

And forty years of forbearance is not something ordinary people can achieve.

It can be said that his heart is as solid as a rock.

But at the same time, he also has the restless heart of a 20-year-old, which often makes Zhao Guoqing feel separated.

He needed time to soothe this feeling.

"I know, Teacher Bi!"

Engineer Bi shook his head slightly and opened the document.

"Feasibility study report on gallium nitride light-emitting semiconductor technology? National Day, is this your paper?"

General Engineer Bi raised his head and looked at Zhao Guoqing. It was not just a long and empty speech. What he was most afraid of was that Zhao Guoqing used these foreign publications to piece together and prove that transistors are the future.

Many young people are like this, coming up with shocking conclusions, and then after the final argument, they just sensationalize.

Looking further, Mr. Bi's face was a little distorted.

Gallium nitride semiconductors emit blue light. This phenomenon was discovered twenty years ago. At that time, experiments demonstrated that the luminous efficiency was too low, only a few dozen lumens per watt.

This discovery was abandoned at the time, and researchers around the world turned to studying silicon carbide semiconductors.

Five years later, Osamu Nakamura, Hiroshi Amano, and Isamu Akaki from Little Japan picked up gallium nitride from the garbage dump. They unexpectedly discovered that adding a layer of gallium nitride epitaxial layer to the silicon substrate can The light efficiency of gallium nitride is greatly increased by more than ten times.

Three people also won the Nobel Prize in Physics.

This is applied physics, which is often discovered accidentally. The ultra-high light efficiency makes commercial use of gallium nitride possible. Dozens of patents have been registered for the extended manufacturing process and blue light-excited phosphors.

Until 2023, national manufacturers are still paying patent fees for this.

At this time, General Engineer Bi looked at Zhao Guoqing from time to time, originally thinking of criticizing a few words.

But the further back I look, the less confident I become.

"Boundary hole theory!"

"Gap electron excitation!"

"..."

Let's just call it a paper. It is well-founded and well-founded. It not only quotes foreign publications, but also the theoretical analysis above makes Mr. Bi speechless.

He had never seen many formulas before. He tried to deduce them and found nothing wrong. Experimental verification was needed.

He couldn't understand some field effect theories.

"Can it be solved by adding this epitaxial layer? Is there any practical proof?"

Zhao Guoqing shook his head and said: "Theoretically, this is true. Now we need experimental verification."

"Experiment, you also said above that this epitaxial layer must be very thin, perhaps at the nanometer level. Can it be done now?"

As expected, Zhao Guoqing had a unique vision and gave General Engineer Bi a thumbs up. He immediately saw the key point.

The manufacturing process of the epitaxial layer has always been the biggest obstacle to the commercial use of gallium nitride light-emitting semiconductors.

Gallium nitride crystals are easily decomposed and cannot be coated with steam. Initially, they were synthesized and precipitated with compounds in an ultra-vacuum environment.

The cost is extremely high and the yield rate is extremely low, making gallium nitride light-emitting semiconductors expensive.

And Zhao Guoqing has been here since 2023, so he naturally knows the most economical and simple manufacturing process.

"Teacher Bi, I have a solution!"

"Do you have any idea?"

Not only gallium nitride, but also gallium phosphorus nitride, aluminum gallium nitride, indium gallium nitride, they are all treasures!
