Although Leiden has no teaching position in the department, no teaching assignments, and little contact with new students, he is no stranger to the name Evan Warren.

Before the holidays, Leiden had heard about the gifted first-year student from several friends who were teaching assistants for the course. I heard that in order to preemptively admit this student, there was even a conflict between PME and the professor of the Department of Chemistry and Chemical Engineering next door.

Therefore, when he heard that this legendary student actually came to the door, Leiden had to say that he was indeed surprised.

So, as soon as he saw Evan, he jokingly said when he shook hands with him: "Evan, you came to me, don't say you want to come to be my student?"

"If so, then I won't want to walk into the PME building next semester. ”

will be divided by a group of red-eyed professors.

Evan looked at this senior who looked somewhat similar to Leonardo in the later period, smiled, and also joked: "If I nod my head, will the doctor kick me out of the door in the next second?"

This answer made Layton stunned for a moment, and then the two of them smiled similarly.

The answer, of course, is no.

As a Ph.D. from Caltech, I still have this pride. Even if Evan really wanted to be a student of Leiden, Leiden dared to accept it.

Even now he doesn't even have a teaching position.

But Evan isn't in his first year yet, and by then, Layton will definitely have a teaching position at Caltech.

The two sat down on the couch, and the old woman brought the freshly brewed black tea, and Evan got up and thanked the old woman.

The old woman was full of smiles, she liked Evan very much, and before going upstairs, she specially asked Leiden to have a good chat with people and help them if they were in trouble.

The old lady thinks Evan is a student and comes to Leyden for help.

"Evan, I won't talk about the extra gossip, how about you be more direct?"

Layton poured tea for Evan and said, "I thought about it, and I didn't understand what you came to me for?"

"Thank you!" Evan took the teacup from Layton's hand and said, "Then I'll be straight to the point." ”

"Dr. Layton, I've read your article, you're one of the few people in our department who studies solid state physics. So, I'd like to ask you to do me a favor......"

Layton picked up his teacup, took a small sip, and waited quietly for Evan's next step.

"I had an idea for semiconductors and wanted to apply for a project, but you know, I'm still a student, and the university can't allow me to do that, so I can't get funding, I can't apply for equipment, and I can't apply for cooperation in the name of Caltech. Of course, for me, funding is not the focus, the latter two are the key. ”

"I asked, and you're a solid state physics student in the department, so I have an idea. ”

"Dr. Leiden, how about our partnership, you are a postdoc and have the right to choose your own topic. ”

"I'll hang the subject with you......"

Hearing this, Layton frowned.

"Of course, if you're interested, you can get involved. Want to hear what my idea is?"

Hearing this, Layton put the teacup on the low table, looked at Evan and said, "If you don't say the last sentence, I will really kick you out." ”

"And now?"

Evan asked with interest.

Layton stretched out his hand and motioned for Evan to get started.

"Leiden, you do solid state physics, I definitely don't need to talk about what semiconductors are, and you definitely know what applications it can have. ”

"Of course, the rectifiers in the radio are made of semiconductors, most of them cuprous oxide, but silicon and germanium are also good materials," Leiden chimed in. ”

"Very well, doctor, then I don't need to say anything later, you know what I want to do after reading this article?"

As he spoke, Evan took out a folded article from the inside pocket of his jacket, unfolded it, and handed it to Layton.

Layton took it and said, "PhysicalReview?"

He gave Evan a strange look in his eyes.

Evan waved his hand and said, "Don't get me wrong, this wasn't ripped from the library, I subscribed to it myself." ”

Seeing Evan say this, Layton continued to watch.

After a while, Layton finished reading this very short article, and after thinking for a moment, he looked at Evan and asked, "This Bardeen said that the properties of surface states can help control the carriers inside semiconductors...... Do you want to follow this line of thought?"

Evan nodded and asked, "If this idea succeeds, how do you think the world will change?"

"If you can control the conductivity of semiconductors, you can make switches, and as long as the switch is not very large, the tube can be replaced......," Leyton speculated.

Thinking of this, Layton slapped his thigh violently, stared at Evan with blazing eyes, and said, "I'll be this partner, let's say, when will you start working, and how about tomorrow?"

Leyton was so eager that Evan understood. Judging from the articles that have already been issued, Evan's idea must have been thought of. Now it's a matter of who made that thing first.

So time is of the essence.

Still, Evan kept Layton down.

"Don't worry, this idea was first proposed by Shockley from Bell Labs, and we haven't heard of any new developments yet, so we should still have time. ”

"What's more, even if we are in a hurry now, we don't have the experimental conditions for a while, the simplest, can you get the germanium single crystal for the experiment?"

"So, in the next few days, we will first prepare the data and design the experimental plan, how about it?"

When Evan said this, Leiden thought about it and could only nod.

……

While Evan and Layton were talking, two beautiful figures on the Caltech campus attracted the attention of pedestrians.

These two are none other than Virginia and Linda.

The two girls came in the morning.

Virginia accompanied Linda and visited almost every place Evan might have been on campus.

Except for certain places where they can't get in.

During these hours, Linda went to the public dining hall of the Blacker House, stood outside room 111 for a few minutes, went to the library where there were still quite a few people, went to the classrooms with closed doors, went to the small gardens under several buildings, and rested on the benches for a long time until someone came up to talk to her.

Eventually, they returned to the OliveWalk trail near Hovses.

Linda looked at the entrance of Hovses from afar, her eyes foggy.

How she wished she was one of them!

It's a pity that this is not possible.

Virginia looked at Linda and sighed softly.

"Linda, are you still reluctant to give up?" Evan's attitude was already obvious. ”

"In the three months you've been in Los Angeles, he hasn't come to look for you once, let alone look for you, and he's only been here once where we live......"

Virginia didn't say any more, for Linda had already turned her head and looked at her with a faint but determined look in her eyes.

Alas!

She could only sigh again.
