On February 27, he received an invitation from California Polytechnic. Researchers with certain strength in the fields of solid physics, semiconductors, materials preparation, etc. arrived in Pasadena, Los Angeles one after another.

These people not only have scholars from universities, but also researchers from industrial enterprises, such as IBM and Western Electric Corporation, have sent people.

Most of these people are old and in total, the oldest of them are only in their early forties.

What made Evan a little happy was that the people from Bell Labs and Purdue University were here.

Although the person from Bell Labs was not any of the three people he wanted to meet the most, Evan was a little disappointed.

Most of these people stayed in the residence prepared by the organizer, not a high-end hotel, but a graduate dormitory on campus.

A small number of people wanted to visit Hollywood, so they stayed directly at hotels in Hollywood.

On the 28th, the Physics Mathematics and Electronic Engineering Building, Warren Leiden Solid Physics Laboratory.

After a month of preparation, the laboratory, which was originally like a grass-roots team, has been completely renovated, and all experimental equipment is newly equipped or made.

With the strong support of the school and the joint efforts of new lab members, the laboratory has been able to prepare high-purity germanium crystals by itself this month. Although the quality may be lower than that of Bell Laboratory and Purdue University, the point-contact transistors made with it can work normally. In this regard, Evan is very satisfied.

In order to make germanium crystals and develop corresponding surface treatment equipment, Evan spent most of this month in the laboratory. In terms of hard work and diligence, it can be said that Evan's peak in his life.

Of course, there is a reason Evan is so diligent.

Most of the technology in the semiconductor industry is in its preparation process. Only by mastering advanced processes can we divide this huge cake.

In addition, the imminent point is that the germanium crystals obtained from Bell Labs are only a little bit and they are gone after using them.

Evan didn't believe that Bell Labs would be so generous to sell him germanium crystals.

At nine o'clock in the morning, Professor Watson, the director of the laboratory who came forward to serve as the reception, walked towards the laboratory with his group.

Professor Watson will first take people to visit the laboratory, and then go to the next door to watch the demonstration experiment.

"Dear colleagues, this is Warren Leiden Solid Physics Laboratory."

At the door of the laboratory, Professor Watson pointed to Evan who had been waiting at the door and said, "Although most people know each other, I still want to introduce it again, because it seems that someone didn't arrive at yesterday's welcome dinner... This is Evan Warren, the backbone of our laboratory and the inventor of transistors."

"Stop rubbing your eyes. Your eyes are not wrong. It's this young man!"

Professor Watson pointed to a participant in the crowd who was rubbing his eyes and made a joke.

Everyone then burst into laughter.

"Okay, I'll leave the next work to this young man. He will lead everyone to visit the laboratory. I can't do this. After all, there are a lot of equipment inside. I don't know what to do."

"Thank you, professor!" Evan took the conversation, reached out to make a call inside, and said with a smile: "Everyone, please come with me, it's the future inside, please do not leave it."

An hour later, the people who had visited the laboratory moved to the next door.

The demonstration experiment will be hosted by Leiden.

"Come on!" After Evan brought the visitors in, he came to the podium. Seeing that Leiden seemed a little nervous, he patted his shoulder and said, "Look at you."

Leiden picked up the water cup on the podium and took a sip, then pulled the tight collar, hesitantly said, "Evan, why don't you talk..."

Evan shook his head and encouraged, "Don't be nervous, you can do it."

Leiden still had a bitter face, and Evan said, "Hey, the Leiden I know is not such a timid person."

"Of course I can change to it, but, Leiden, are you willing to be willing to be willing to be all the honors and all the credits belong to me alone?"

"The transistor is yours, Evan!" said Leiden.

Evan waved his hand and said, "No, I'm not just talking about transistors."

"Leiton, let's not talk about anything else, are you the ones who solve the problem of preparing germanium single crystals? Are you working hard on several important equipment in the laboratory next door?"

"So, don't hesitate there. You don't just take advantage of it or work hard. You don't have to underestimate yourself, let alone feel guilty."

Perhaps Evan was talking to the point, Leiden looked at him and said, "Do you really think so?"

Evan nodded.

In Evan's opinion, Leiden is a good collaborator, and Evan is happy to help him.

"Huh!" Leiden gave out a long breath when he saw this, then raised his chest and said, "Since you said so, okay, look at me."

"Leave it to you!"

After saying that, Evan patted Leiden on the shoulder again and came to the door.

At this time, a participant walked towards him.

"Hello, Evan Warren, can you talk?" The man extended his hand to Evan and introduced himself: "My name is William Gordon Pfan, from Bell Labs."

Evan shook his hands and said, "Of course, this is my honor."

This is the first meeting between the two.

Pufan stayed in Hollywood yesterday and came to Pasadena today.

He is one of the people who did not attend last night's dinner by Professor Watson.

Pufan found Evan and did not mention the fact that he cheated germanium single crystals from Bell Labs. Instead, he was more concerned about Evan's lab's obviously homemade equipment.

For example, the equipment for preparing germanium single crystals.

After some exchanges, Evan learned that Pufan's major is materials, and he is responsible for the research on material preparation in Bell Laboratory. He has made contributions to the purity of germanium single crystals in Bell Laboratory.

Pufan was very interested in Evan's equipment and asked many technical questions. Evan gave a detailed or brief answer based on the situation.

Of course Evan didn't say something about the core secrets, and Pufan naturally understood this.

After several questions were exchanged, the demonstration experiment on Leiden had begun, but Pufan had no intention of ending. Evan asked: "Mr. Pufan, don't you go in and listen?"

Pufan just glanced at the experimental device on the podium and replied: "No, your contact transistor, Bading, oh I'm talking about the people in our laboratory, and they have figured it out. It doesn't matter whether I look at it or not."

Evan nodded slightly, then said, "I'll ask you, what do people in your laboratory think of this point of contact transistor."

Pufan looked at Evan with a smile and said, "They are all angry and say you are a thief."
Chapter completed!
