Chapter 388 The King among Physics Celebrities (Third update, please subscribe)

While Jiangdong and his classmates were sweating and playing football on the playground, in other parts of the school, some people were studying in the library, some were catching up on homework, and some were obsessed with research.

In short, at this time, Kuching University is like all universities in Nanyang. Although it is the weekend, everyone is busy, and the same is true for sports. A better body is for better research.

At about five o'clock in the evening, it suddenly started to rain.

In fact, the rain is not sudden at all. After all, it is the rainy season, and sunshine is an accident.

The sultry weather immediately became much cooler, but the rain was also very annoying. After all, everyone knew that it had entered the rainy season, and once it started raining, it might not stop.

Although it started to rain, the temperature was not low, and the indoor temperature was not low either. The mercury on the thermometer was still stable at 32 degrees, and the weather was still very hot.

Chen Shuzhe, who had been busy in the warehouse for a day, felt a little tired, but still had no intention of taking a rest. When he stared at the equipment in the warehouse, his eyes became a little excited.

Last year, after Li Yi'an proposed the semiconductor "PN junction", how to transform the theory into reality and successfully develop a "PN junction transistor" has become the focus of research by scientists from various countries. During this period, scientists proposed various feasible methods. The most important achievement was the idea of ​​"single crystal", which sparked people's thinking.

It also inspired Chen Shuzhe. He boldly proposed an idea - a semiconductor "single crystal". He believed that it was necessary to create a large "germanium single crystal" before doping P or N junctions was possible.

The next step was to manufacture the corresponding equipment. Although his concept did not receive support from the outside world, as a lecturer in the Department of Chemical Engineering at the University of Kuching, he jointly designed and manufactured it with the help of two colleagues from the Department of Mechanical Engineering. A simple piece of equipment capable of growing crystals. This piece of equipment uses a simple machine made of a large rolling door drive device and an induction coil. Although it sounds simple, this piece of equipment is enough to be recorded in human civilization. History, its emergence will change everything.

"Continuous Czochralski method,"

Chen Shuzhe said as he lit a cigarette and took a long puff.

"This is Polish scientist Jan Tchaikolaski. He invented this method when he was studying the crystallization rate of metals in 1916. However, this method has not been taken seriously by the outside world. I think this method can completely A germanium single crystal was produced.”

"Teacher Chen, as long as you decide, let's start."

Lin Shudong and Wen Qianyi laughed at the side.

They are university colleagues and also university alumni. They both graduated from Southwest Associated University. After joining the search team 4 years ago, they were sent to study in the United States. After arriving in Nanyang, they were assigned to Kuching University. The relationship between alumni and comrades is natural. Far more than anyone else, which is why they have no complaints about the Czochralski equipment they helped research.

After taking a strong puff of cigarette, Chen Shuzhe and the others got busy. They connected the power supply to the graphite resistor and started heating. They melted the polycrystalline germanium in the high-purity quartz crucible, then inserted the seed crystal into the surface of the melt for welding, and installed the end The seeded rod is slowly lowered into the molten germanium. The rod rotates in the counterclockwise direction and the crucible rotates in the clockwise direction. Then, the rotating rod is lifted upward very slowly, so that a nearly cylindrical germanium crystal rod can be formed below. By continuing to pull...and then slowly, slowly "pull it out," you end up with a long, narrow germanium single crystal.

When the germanium single crystal was pulled out, Chen Shuzhe and the others had full smiles on their faces.

"OK, successful!"

There was no ecstasy as imagined, only a faint sense of relief, as if this moment was a matter of course.

There was no sudden inspiration, only eleven months of hard work and dedication. After much sweat, finally, at the end of 48 years, they pulled out the world's first germanium single crystal.

After the formation of the single crystal, there were rave reviews for Chen Zheshu and others, and all kinds of admiration were like the endless flow of a surging river, or like the Yellow River flooding out of control.

After the successful production of germanium single crystal, the development of PN crystal transistors was like taking something from a bag. A goal that was once out of reach seemed to be right in front of us and became within reach. Xiao Guangchi, a chemist at Changhong Radio Laboratory, took the lead in adopting Chen Zheshu's method for the first time. By dropping tiny impurity particles into molten germanium during the crystal growth process, a very crude PN junction was finally formed. This was also the world's first a PN junction.

Unlike in 47, it took several months before he learned about the invention of the transistor. This time, Li Yian learned the news immediately. After all, this meant that his theory became a reality.

For a time, physicists from all over the world sent congratulatory messages to Li Yian without hesitation. Once upon a time, the concept of PN junction was not far away from the "king's fantasy" in the eyes of many people.

Now, it's finally been confirmed.

For a time, the admiration for Li Yi'an, a great physicist, from all walks of life was like an endless stream of water, or like the Yellow River flooding out of control. In short, once upon a time, he was a king, and now, he is a great physicist with the title of king. Although at this time, everyone does not know how the PN junction transistor will change the world, but the icing on the cake is that everyone is familiar with it.

In the face of compliments from the outside world, Li Nian seemed very calm. While congratulating Chen Shuzhe, Xiao Guangchi and others through the spokesperson, he left the presidential palace.

Although he was very excited in his heart, he seemed to have accepted the surprise now.

They made an appointment with Yuan Jialiu to meet at the reservoir near Science City. When Yuan Jialiu met Li Yi'an, he was fishing by the lake. He looked... not like a physicist at all.

“Fishing is a lot of fun!”

Hearing the footsteps, Li Yian said without looking back. His eyes were always fixed on the slightly rippled water.

"This reservoir is stocked with carp and grass carp that are not found in Borneo. The carp you eat in restaurants in Chang'an is only found in this reservoir."

"I don't know that."

Yuan Jialiu sat next to him, picked up the fishing rod and said,

"I thought they existed here originally? I didn't expect that like tigers, they were introduced from Tangshan."

"It's a South China tiger." Li Yian fixed the fishing rod, stood up and stretched his shoulders.

"The South China tiger is a tiger species unique to Tangshan. Well, I introduced 137 tigers from Hunan, Guangdong and Fujian provinces and released them in several nature reserves. They are no different from local animals. They have been They have taken root here, just like us. Oh, by the way, we have also released fifty-six Baiji dolphins in the Capuas River and the Barito River, and now they have begun to breed..."

When mentioning these wild animals that disappeared in another world, Li Yian looked quite proud.

These animals are all species unique to China, but they have become extinct due to various reasons. In order to make up for some regrets, while introducing immigrants, Li Yian also introduced these animals that would become extinct, and even introduced the Yangtze River white sturgeon, but the latter Breeding is limited by temperature, migration and other reasons, and is not very successful. However, zoologists have still found ways to artificially breed them in plateau rivers.

In the future, perhaps one day, they will return to that land and continue to thrive on that land where they have lived for hundreds of millions of years.

After a pause, Yuan Jialiu expressed his congratulations directly to Li Yian.

"Thank you, actually..."

Li Yian smiled.

"Compared to my theory, I care more about our people and realizing it."

"Indeed, it was our people who made it happen. It was not easy."

Yuan Jialiu naturally understood the meaning of his words. It is better for our own people to realize this theory than for outsiders to realize it first.

"We are now catching up with European and American countries in various fields, including semiconductors. The whole world is on the same starting line. As long as we seize the opportunity, we still have great hope of leading the world."

The surprise at Kuching University made Li Yi'an think a lot. Even coming to fish is to calm down and think about some things, such as how to guide the next step?

How to achieve the development of 1+1 greater than 2?

No answer yet.

However, he turned to look at Yuan Jialiu and said.

"How's it going? Are you getting used to it in the institute?"

After Yuan Jialiu and his wife came to Nanyang, they entered the Institute of Physics and continued to engage in physics research and teaching.

"There is nothing uncomfortable about it. I just engage in physics research as before. The environment is much better than in the United States. At least, this is my home."

"Home", for overseas wanderers like Yuan Jialiu, "home" is an extremely special existence. No matter how good the United States is, it has never been his home, but Nanyang is their home in a certain sense.

"Home……"

Nodding slightly, Li Yian said,

"There is one thing I need to tell you in advance...we are going to develop an atomic bomb."

Yuan Jialiu almost blurted out,

"Does Kenxiong need to participate?"

Nodding, Li Yian said.

"After the plan is launched, my sister-in-law may need to leave Science City temporarily."

After taking a deep look at Li Yian, Yuan Jialiu thought for a while and said,

"Maybe... I can help too."

As a physicist, Yuan Jialiu can indeed help, said Li Yi'an, who had already expected this answer.

"The research on atomic bombs is of great importance. We will conduct research in this area in a completely closed environment. At that time, it may affect your academic achievements."

This was a reminder between friends. Yuan Jialiu frowned, his face seemed a little unhappy because of this reminder.

Yuan Jialiu glanced at the lake that suddenly became rippled.

"A fish is hooked!"
