On February 27, after receiving an invitation letter from the California Institute of Technology, researchers with certain strength in the fields of solid state physics, semiconductors, and material preparation arrived in Pasadena, Los Angeles one after another.

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

Most of these people are menstruating, and the oldest of them is only in his early forties.

To Evan's somewhat delight, people from Bell Labs and Purdue University came.

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

Most of these people stayed in the accommodation prepared by the organizers, which was not a high-end hotel, but a graduate dormitory on campus.

A small number of people want to stop by Hollywood, so they stay directly in Hollywood hotels.

On the 28th, the Physico-Mathematical and Electronic Engineering Building, the Warren-Leiden Solid State Physics Laboratory.

After a month of preparation, the original grass bench team-like laboratory has been completely renewed, and all the experimental equipment is newly equipped or newly made.

With the strong support of the school and the joint efforts of the new members of the laboratory, the laboratory has been able to prepare high-purity germanium crystals by itself in this month. Although it may be a little worse than Bell Labs and Purdue University in terms of quality, the point contact transistors made from them are already working properly, and Evan is very satisfied with that.

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

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

Most of the technology of the semiconductor industry is in its preparation process, and only by mastering the advanced technology can we have a share of this huge cake.

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

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

At nine o'clock in the morning, Professor Watson, the director of the laboratory, who came forward to serve as the reception, led a group of people to the laboratory.

Professor Watson will take people on a tour of the lab and then go next door to see a demonstration experiment.

"Ladies and gentlemen, this is the Warren-Leiden Solid State Physics Laboratory. ”

At the door of the laboratory, Professor Watson pointed to Evan, who was already waiting at the door, and said, "Although most of us have known each other, I still want to introduce it again, because it seems that no one arrived at the welcome dinner yesterday...... This is Evan Warren, the backbone of our lab, the inventor of the transistor. ”

"Don't rub your eyes, your eyes are not wrong, it's this young man!"

Professor Watson made a small joke by pointing to one of the participants in the crowd who was rubbing his eyes.

The crowd burst into soft laughter.

"Okay, I'll leave the rest of the work to this young man, he'll show you around the lab, I can't do that, after all, there's a lot of equipment in it that I don't know what to do. ”

"Thank you, Professor!" Evan took over the conversation, stretched out his hand to make a gesture of inviting inside, and said with a smile: "Everyone, please come with me, inside is the future, please be sure not to fall behind." ”

An hour later, the crowd moved next door after touring the lab.

The demonstration experiment will be hosted by Leiden.

"Come on!" Evan brought the visitors in to the podium, and when he saw that Layton seemed a little nervous, he patted him on the shoulder and said, "It's up to you." ”

Layton picked up the glass of water on the podium and took a sip, then pulled his tight neckline, and hesitated: "Evan, or you should talk about it......"

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

Layton still grimaced, and Evan said, "Hey, the Layton I know isn't such a timid person. ”

"Of course it's okay to replace me, but, Leiden, are you willing, willing that all the honor and all the credit belong to me alone?"

Layton said, "The transistor belongs to you, Evan!"

Evan waved his hand and said, "No, I don't just mean transistors. ”

"Leiden, not to mention anything else, is it you who solves the difficulty of preparing germanium single crystals?

"So, don't hesitate there, you don't just take advantage of it and don't make any efforts, so you don't have to be presumptuous, let alone feel empty. ”

Perhaps because Evan was on his mind, Layton looked at him and said, "You really think so?"

Evan nodded.

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

"Whew!" Layton let out a long breath when he saw this, then puffed up his chest and said, "Since you have said so, okay, look at me." ”

"Over to you!"

With that, Evan patted Layton on the shoulder again and came to the door.

At this moment, one of the attendees approached him.

"Hello Evan Warren, can you talk?" the man introduced himself as he held out his hand to Evan, "My name is William Gordon Pufan, and I'm from Bell Labs. ”

Evan shook his hand and said, "Of course, it's my pleasure." ”

This was the first meeting between the two.

Pufan stayed in Hollywood yesterday and only came to Pasadena today.

He was one of the people Professor Watson said did not attend last night's dinner.

When Pufan approached Evan, he did not mention that he had cheated germanium single crystals from Bell Labs, but was more concerned about the apparently homemade equipment in Evan Labs.

For example, the equipment for the preparation of germanium single crystals.

After some exchanges, Evan learned that Pufan's specialty is materials, and he is responsible for the preparation of research materials at Bell Labs, and he has a part of the credit for the high purity of germanium single crystals in Bell Labs.

Pufan was very interested in Evan's equipment and asked many technical questions, which Evan gave in detail or briefly, depending on the situation.

Something that involves the core secret, of course, Evan didn't say, and Pu Fan naturally understands this.

After exchanging a few questions, the demonstration experiment on Leiden's side had begun, but Pufan had no intention of ending, and Evan asked, "Mr. Pufan, won't you go in and listen?"

Pufan just glanced at the experimental device on the podium, and then replied: "No, you touch the transistor at this point, Bardeen, oh I'm talking about the people in our lab, it's already figured out, it doesn't matter if I look at it or not." ”

Evan bowed slightly, and then said, "I take the liberty of asking, what do the people in your lab think of this point contact transistor." ”

Pu Fan looked at Evan with a smile and said, "They are all angry and say that you are a thief. ”

"Of course, that's their opinion, and it seems to me that they're just running away from the facts. He shrugged his shoulders and said, "So, I am the only one who has invited you." ”
