Chapter 497 Transistor Successfully Developed

Reinhardt can't go wrong. The last Spanish gold harvest, Reinhardt operated very successfully. Cyric believes that this time the French gold will also be in the bag.

With this batch of gold, the German business will surely be successful! Cyric believed that with his travels, this time and space was different from history.

Reinhardt left. It was already dark outside. Before he knew it, it was another busy day. Cyric patted his mouth and yawned. He didn't go home for several days.

The battle situation has stabilized, and I have nothing to worry about. Now, I don't have to be afraid of someone timid. Now, everyone is a joy of victory.

Go home.

Standing up, just as he was about to put on his coat and go home, his coat threw a pile of documents on the table to the ground.

This pile of documents had just arrived. Cyric looked at the pile of documents and shook his head. As a head of state, there would be a lot of work to do every day. Perhaps, only a model worker like Zhu Yuanzhang would like this kind of work. Live it.

He looked down and glanced, and suddenly, his eyes were full of surprise.

A report is in sight.

GEMA has successfully trial-produced a PN junction transistor!

Cyric, from the afterlife, certainly knew what that meant.

Transistors can be regarded as opening a new door to electronic technology. The integrated circuits of later generations are developed on the basis of transistors. The basis of microelectronics technology is transistors!

Cyric is very concerned about the aspect, and has given guidance several times, hoping to fiddle with transistors as soon as possible.

Once, under Cyric's proposal, the miniaturization of electronic tubes has been carried out smoothly, and the volume of various electronic tubes has been successfully reduced to one-tenth of the original.

However, this is already the limit of electronic tubes. Future technology is absolutely inseparable from transistors. Computers, radars, sonars, and various electronic devices all require a large number of transistors.

This is an age-defining discovery!

"Führer, do you want to go home?" the guard Graf asked Cyric.

"No, go to GEMA," Cyric said.

He couldn't wait.

In World War II, many kinds of technologies were born, more than in the past 100 years. It can be said that war is a catalyst.

In the car, Cyric continued to rejoice, opening the door to microelectronics.

what does that mean? Our own precision guided weapons can be further optimized to reduce costs. Our own radars can be smaller, have longer detection distances, and have higher accuracy, and even meet the needs of artillery radar guidance!

Our own wireless telegraphs will also be lighter and easier to implement our own frequency hopping encryption technology.

Historically, it was not until December 1947 that Bell Labs in the United States successfully developed a point-contact germanium transistor. But in fact, the development of semiconductors has already begun.

In the first decade of the 20th century, communication systems have begun to use semiconductor materials. For example, ore radios use semiconductor materials for detection.

As for the invention of the transistor, it can be traced back to 1929, when engineer Lillian Feld had obtained a patent for a transistor.

However, limited by the state of the art at the time, the materials used to make such devices were not of sufficient purity to make such transistors impossible to manufacture.

During the Second World War, many laboratories also made a lot of achievements in the manufacture and theoretical research of silicon and germanium materials, which laid the foundation for the invention of the transistor.

It can be said that these technologies have already laid the groundwork, but more financial resources, material resources and manpower are needed to focus on tackling key problems.

Other countries may not realize the great significance brought by transistors, but Cyric is clear that in future generations, without microelectronics, it is impossible to move an inch.

Moreover, Cyric was born in engineering, and of course, he is quite familiar with electronic circuits, and he is also quite familiar with the most common PN junction in transistors.

The only thing needed is to use the industrial technology of this era to make it!

"Crench," the car stopped. GEMA, has arrived.

This was originally just a small company, but with Cyric's support, the company's scale has expanded hundreds of times. Now GEMA is the most important radar development and production company in Germany, and it is also a secret department.

For example, at the gate, there is the Gestapo to guard.

Cyric's car stopped directly in front of the building, which was the company's research institute. At this time, Dr. Hollmann, who had just received the news, ran out in three steps and two steps.

His documents were sent three days ago. Documents from scientific research institutions in the rear like him had to be placed behind the military's intelligence, so it took a few days before they were reported.

When he learned that Cyric was coming, he was extremely excited, and when he saw Cyric getting out of the car, he could not hide his excitement: "Great Führer, you are really a genius, we will follow your vision, Successfully made new electronic components, which is a great invention!"

Using different doping processes, the P-type semiconductor and the N-type semiconductor are fabricated on the same semiconductor substrate through diffusion, and a space charge region is formed at their interface, which is called a PN junction.

The PN junction has unidirectional conductivity, which is a characteristic utilized by many devices in electronic technology, such as the material basis of semiconductor diodes and bipolar transistors.

At this time, Dr. Hollmann told Cyric incessantly: "We have tried many times according to your design plan, and initially failed. We realized that the purity of our own semiconductor material was not enough. We adopted The new vacuum smelting equipment can finally purify high enough germanium, and then realize this great invention!"

For semiconductors, the most important thing is the purity of the material, which can only be purified by smelting in a vacuum.

This is of course inseparable from high investment, otherwise, no scientific research has such strength.

Cyric nodded: "Germanium transistors can be industrially produced, and by continuously improving technology, costs can be reduced. At the same time, silicon semiconductor transistors must also be developed."

Now, the cost is very high, but Cyric believes that it will come down soon. As long as you have heard of Moore's Law, you will know the speed of replacement of electronic products.

There are several kinds of semiconductor materials, but there are only two suitable for making transistors, especially silicon and integrated circuits, which are completely made on silicon wafers.

"We have done research and found that if the radar uses a large number of transistors, the reliability will be improved by about a hundred times." Dr. Hollmann showed a prepared transistor to Cyric and placed it in his hand, which was about the size of a peanut.

There is no filament, no grid or anything, any vibration will not affect the operation of this electronic component, and its reliability is quite high.

(I made another mistake, and I nagged a chapter. As a physics teacher, I really admire the gate of transistors. Now everyone reads books on mobile phones, and they have to thank the original father of transistors!)
