Military Industry of Great Powers: Build the Strongest Flanker

With enough materials, Zhao Guoqing also let go of the experiment. Director Gao directly approved an idle factory building, put the equipment in it, and built a separate laboratory.

The guard battalion also sent a platoon of soldiers to guard day and night.

The new college students selected two people, Xu Ming, who studied chemistry at H, and Jia Pengfei, who studied physics at S University.

The laboratory is not under the jurisdiction of others. Director Gao reports to Director Gao when he is present, and reports to General Engineer Bi when Director Gao is absent.

Everyone must abide by confidentiality regulations.

In this way, without the knowledge of other people in the 14 institutes, a secret laboratory was prepared.

Due to limited equipment, there is no ion injection machine for doping p-level semiconductors. There are only three such equipment in China, one at the School of Materials at Q University, one at GF University, and one at 5831 Chip in WX City. factory.

"P-level magnesium ion doping process, 5831 can do it, don't worry about National Day!"

Zhao Guoqing nodded. Being in the military industry system has this advantage. You can concentrate your efforts on big things. As long as you want to do it, all the resources across the country can be mobilized.

"General Engineer Bi, can you find some gas masks?"

"What do you need a gas mask for?"

Zhao Guoqing smiled and said: "I saw research in foreign journals that indium antimonide crystals have excellent infrared effects..."

"You want to synthesize indium antimonide crystal? Infrared effect, you mean?"

Zhao Guoqing nodded and said: "I have a basic understanding of the physical and chemical properties of p-group compounds, and I should be able to make them! However, the indium element is poisonous, and it is not easy to do it without protection."

Zhao Guoqing is not sure that this matter is easier than the epitaxial growth of gallium nitride.

As for the infrared characteristics of the indium antimonide crystal, once the crystal is made, it can naturally be tested.

The excellent sensitive properties of indium antimonide make it a good material for military industry.

It is an infrared seeker used in surface-to-air and air-to-air missiles. It has excellent material properties. Even forty years later, the indium antimonide seeker will be irreplaceable.

In an environment where China currently lags behind the West by 20 years, it is particularly important to develop lower-cost air-to-air and surface-to-air missiles.

Understanding the meaning, General Engineer Bi nodded fiercely. He was convinced. A young man who had just graduated had so many ideas, but the key was that they came to fruition.

But when I think about it, something feels wrong.

"Institute 14 is engaged in radar. Indium antimonide should be the research content of the 503 Optoelectronic Infrared Institute. I spend my time and help others make clothes. This matter..."

…………

Director Gao brought his suitcase to the headquarters and went directly to the office of Chief Engineer Zhao Zhongshu.

"Lao Gao, why is the wind chasing you here!"

Director Gao looked solemn and said: "General Master Zhao, I'm here to report to you!"

Zhao Zhongshu was just about to pour a glass of water for Director Gao and talk slowly, but Director Gao stopped him.

"General Master Zhao, let's make the story short!"

"..."

"Okay, you say it!"

"We have made gallium nitride crystals controlled by foreign countries..."

"What do you mean, gallium nitride crystal? How is that possible? Do you know what gallium nitride crystal is used for?"

"People who make radars can also make light-emitting semiconductors. It may be impossible not to mention it first. We should send it to the materials room of the Academy of Sciences for testing first to find out!"

Zhao Zhongshu looked at Director Gao. Institute 14 did not have the conditions to make gallium nitride crystals. He was an expert in materials science and knew what was going on. China now has a dedicated team to research gallium nitride crystals. Until now, it is still I haven't heard any positive news.

"Old Gao, you must be responsible for lying about military information! Where is the gallium nitride crystal you mentioned? Don't make a mistake!"

"OK!"

Director Gao opened the suitcase, which was protected by layers. On a three-inch silicon wafer, a light yellow crystal about one centimeter thick grew.

"call!"

The crystal color is translucent, the growth quality is very good, there are no defects such as bubbles, and the crystal phase should be good.

"General Master Zhao..."

Zhao Zhongshu took out a sesame-sized piece from the corner, looked at it with a magnifying glass, and then threw the gallium nitride crystal into the tea cup.

It can be seen that Crystal and Shuo slowly started to react.

"Less than, come in!"

The door opened, and a young man in Mao suit entered the office.

"Go to the laboratory and get the gallium nitride chip borrowed from Q University!"

"OK!"

After a while, Yu Yu brought the chip over. In the container, a chip the size of a fingernail lay on it. It was about the same thickness as a fingernail, and it was transparent and colorless.

Zhao Zhongshu looked at it for a long time, his expression becoming more serious.

"Bring me a clean vessel!"

"good!"

Chief Zhao took off another small piece and put it in the vessel.

"General Master Zhao, if you continue to deduct it, you will lose it!"

"What do you know? Come on, Director Gao, let's go to the laboratory and have a look!"

Simple identification can be done at the headquarters. Through the flame reaction of elements, the composition of the crystal can be analyzed in the spectrometer.

"Chief Engineer, the results are out, the crystal only contains nitrogen and gallium elements!"

"You really did it!" General Master Zhao looked at Director Gao in disbelief and said, "Put it in a vacuum furnace and heat it to 1,200 degrees!"

The assistant took the materials and continued to test them. General Zhao turned to Director Gao and said, "No wonder you guys at Institute 14 couldn't complete the mission. It turns out that you started to do some evil things. This gallium nitride crystal is not easy to make. It took a lot of effort." , who took the lead?”

"General Master Zhao, this is not a crooked way. You should also read the foreign publications. Foreign countries have begun to use gallium nitride semiconductors in military applications. The miniaturization of radars depends on this stuff."

Zhao Zhongshu nodded and said, "That's right! If you are aggressive, we military industry workers should look at what's in the bowl and what's in the pot."

Outside the vacuum furnace, after a while the furnace was heated to 1200 degrees, and the furnace was lowered to normal temperature. First, the gas inside was removed. Once detected, it was pure nitrogen. Then, looking inside the furnace, there was a silver metal like mercury, although there was very little. , it can also be seen that it is elemental gallium.

There is only one kind of gallium nitride molecular combination. Unlike oxygen and iron, there are iron oxide, ferric oxide, and ferric oxide. The reason is that iron can be either divalent or trivalent.

Therefore, it can basically be determined that it is a gallium nitride crystal. The headquarters cannot determine the specific crystal phase. It requires an electron microscope, which is rare. The department has one.

"Look, the one borrowed from Q University can only be used for non-destructive experiments. There is a bubble on the edge of this crystal, and the quality is not as good as yours!"

"Higher quality than materials controlled abroad? This is Xiao Zhao!"

"Xiao Zhao? By the way, Director Gao, who is taking the lead on this project? I don't remember that you are good at chemistry..."

"General Master Zhao, let's arrange the testing first. I don't know what the quality is like yet?"

"That's right, okay, I'll go with you."
