Chapter 485

MIT laboratory, 4 PM, equipment debugging completed.

Xu Xu Qingzhou had also checked other equipment in the laboratory roughly, although a bit old, it could be used after a little bit of tidying up, which could meet the experimental needs.

Seeing the equipment running smoothly, everyone went to the office next door out of the laboratory.

Xu Xu Qingzhou asked in a deep voice: "Carson, your physics department... are there many portable Raman spectrometers?"

Carson immediately understood Xu Xu Qingzhou's meaning, thought for a while, and said: "Applying for new equipment is very troublesome, but those old equipment in the warehouse should be able to be taken out for use."

Xu Xu Qingzhou wanted to get some equipment, that office is quite big, it's a pity that those positions are empty.

For example, desktop ellipsometers that can directly measure the thickness of ALD-deposited thin films, portable Raman spectrometers, small ultrasonic cleaners, oscilloscopes monitoring low-voltage signals, etc., these equipment can actually be installed in the office.

"I have to go to the Research Management Office."

Xu Xu Qingzhou still decided to find Wilson of the Research Management Office. The laboratory had already been lent to him, so it shouldn't be a problem to borrow some small equipment, right?

He estimated that this could basically complete 80% of routine testing and debugging in the office equipment.

Just do it, let Carson take two rookies to monitor the equipment operation, and Xu Xu Qingzhou went to do business.

Just the debugging of the ALD process takes two days.

For example, optimizing the purge time requires repeated testing, too short leads to a decline in film quality, too long reduces production capacity, and it takes multiple adjustments to find a balance point.

Just as Xu Xu Qingzhou expected, Wilson agreed to the equipment application, and besides old equipment, even gave a brand new desktop ellipsometer.

"Thank you, Mr. Wilson."

Xu Xu Qingzhou was still quite moved, and said when leaving: "Later you will find that this will be a quite cost-effective deal."

Wilson smiled helplessly, not taking it to heart.

Make money?

He didn't believe this project could make money.

Xu Xu Qingzhou walked out of the office, only then noticed a white-haired old man standing outside the door, and, his gaze was fixed on him.

He could only nod politely, and when he left, the old man looked at him deeply again.

"Hiss~"

Xu Xu Qingzhou walked a few steps, couldn't help but look back, the old man had already entered Wilson's office.

"Strange, this old man's look... why is it a bit resentful."

Xu Xu Qingzhou shivered, boys should still protect themselves when going out.

"Mr. Vasquez, please sit. You have this expression, still worried about the student jumping ship?"

Wilson smiled.

That's right, this person is exactly Carson's supervisor Bald Vasquez.

Bald Vasquez sighed, helplessly said: "Carson is my most outstanding student, his talent should not be wasted on ethereal topics."

"Young people are energetic, can't sit still, it's normal to want to make some movement."

Wilson comforted.

Bald Vasquez said: "Young energy is useless... just like Dolly the cloned sheep, many topics were doing it back then, but it's useless, only those who publish first and produce results first will be praised by everyone, everyone only values the results, and won't care how hard they try... the scientific research world is so cruel."

"Hope they can give us surprises like the Riemann hypothesis."

Although Wilson said so, he felt it was impossible at all, the competition in superconducting thin films is too terrible, and the investment is at the million level, Xu Xu Qingzhou's little funds are not enough at all.

This research group is more like young people playing house.

"Okay, now we should talk about business, what problem do you have coming to me?"

"Funds for the third phase..."

"Oh, it's the damn funds again!"

A rain of autumn fell in early September, as if entering autumn overnight, the red leaves by the Charles River and the ancient buildings complemented each other.

Xu Xu Qingzhou went to the classroom first, Wilson led Sun Sun Simin and Ma Ma Ersi to do the final debugging.

26 people selected, but there were at least sixty people in the classroom.

Xu Xu Qingzhou walked in, the classroom gradually quieted down, he looked around, and opened his mouth: "Good morning everyone, welcome to my classroom, before class, please allow me to make my classroom guidelines clear..."

Everyone might discuss Xu Xu Qingzhou's superconducting thin film experiment, but no one doubted Xu Xu Qingzhou's strength in mathematics.

Four mathematical conjectures are placed there.

A double big shot mathematician of the Fields Medal and Wolf Prize.

His class is naturally hot.

If you can't grab the class, you can only come to rub it, ask a question or something.

Even some scholars of oscillatory integrals will come to listen, wanting to see if there are any brand new ideas, or exchange ideas after it ends.

For example, just like playing a game, attending a mathematics class is like a top player telling about their own play style, where it is easy to be stolen, what node should be done, shaping the thinking of thinking about problems.

The first lesson, introduction and basic concepts.

Today mainly expounds the definition and classic examples of oscillatory integrals: \inte^{i\lambda\phi(x)}\psi(x)dx.

Of course, Xu Xu Qingzhou still raised the difficulty a bit, adding some physical motivation, such as wave equations, phase oscillation in quantum mechanics.

Eleven o'clock, finished the first lesson of oscillatory integrals of the new semester, he chewed a burger casually on the road and went straight to the laboratory.

Last Wednesday, small equipment was installed in the office, the office that was not big suddenly became crowded, but it looked more formal, with the feeling of doing experiments.

Xu Xu Qingzhou changed clothes and entered the laboratory, Carson had already done the final debugging.

Xu Xu Qingzhou pulled all the data once, saw no problem, nodded slightly, "Good, officially start the experiment."

"Good."

Staying in the laboratory for a week, Sun Sun Simin and Ma Ma Ersi lost their previous curiosity, opened their notebooks, and prepared to record the experimental steps.

Today planned to start, carry out graphene preparation, this step takes about 8 hours.

The CVD system is MIT's common system Cambridge NanoTech Savannah S200, in order to be able to use it normally, this period of time carefully adjusted the parameters.

Xu Xu Qingzhou put on goggles, performed the first step of copper foil pretreatment, acetone, isopropanol, deionized water in turn ultrasonic cleaning copper foil, nitrogen blow dry.

Half an hour passed.

"Watching Professor Xu do experiments is more interesting than the Super Bowl."

Wilson sighed on the side, all steps were done in one go, no extra movements, it was called smooth.

He was also used to it.

Xu Xu Qingzhou seems to know everything, and is terrifyingly proficient.

Ma Ma Ersi was a bit yearning: "When can I be so powerful."

Wilson rolled his eyes and said: "Don't ask me such a difficult question."

He was thinking about when he could be as proficient as Xu Xu Qingzhou.
