From top student in college to scientific research powerhouse

Chapter 15 I'm a top student too!

All seven sets of data are within the range of values.

I don't even dare to think about it...

Li Jiaxin knew that mathematical models were the latest research, and his old classmate definitely wanted to verify them with real data.

However, when it comes to the relationship between the atomic and electronic layers of the substrate and the characteristics of the device, even the slightest breakthrough in research is remarkable, and in most cases, there will be no progress at all.

The typical result is that half of the values are within the range, and half are outside the range.

This result is essentially meaningless, which means that the mathematical model has failed to be developed.

Most of the data are within the range, and a few validation data exceed the range, which indicates that the model has the potential for improvement. However, because there is data within the range, even if improvements are made, the practical application significance is not great.

The data verification showed that all values were within the acceptable range, a result that was unimaginable.

After reviewing the data analysis, the original numerical calculations, and the results of the substitution calculations, Li Jiaxin confirmed that there were no problems with the verification process and immediately went to find Shi Yaokun.

Shi Yaokun was also stunned by the result, "All the verifications are within the range?"

"This model is amazing!"

He immediately decided to have anyone with free time help with data verification.

The research base has a lot of experimental data on substrate manufacturing of semiconductor materials. We collected a large amount of data, performed data analysis and calculations, and then substituted it into the model for verification. The results came out quickly.

"All sixty-seven groups are within range!"

Li Jiaxin kept a close eye on the data verification process, but he was still very surprised when he finally announced the result: "This model is correct!"

He also understands the significance of the model being correct: "In other words, semiconductor device manufacturing will have a completely new theoretical foundation, and it will be a directly computational foundation."

"We can use models to calculate what type of substrate material is needed for the required semiconductor devices."

"The model does not include all parameters, but it is still an important indicator. For example, the electromagnetic properties of the device are included..."

"Currently, the premise is that it can be further improved, and it would be best to further narrow down the scope."

Li Jiaxin finished speaking in one breath.

The parameters of a mathematical model are all within a range of values; even if they are correct, the calculation can only provide a reference.

Further improvements could be made, for example, by significantly narrowing the range of values, or even by turning the parameter range into numbers.

At that time, we will be able to determine, through calculation, what type of substrate material should be used for semiconductor devices.

The difficulty of research and development will be greatly reduced, and technological breakthroughs will become easier.

Shi Yaokun took a deep breath and decided, "Engineer Li, get ready. We'll be going to Jiangzhou next week."

"Meet with your old classmates, and also figure out the problems with the model: who did the research? Can it be further improved?"

"If possible, we'd like to try and cooperate!"

……

Jiangzhou University.

Zhang Minghao spent a few days in a fulfilling life of studying and exercising. He would go for a run in the morning, attend classes during the day, and spend the rest of his time in his workspace reading papers and materials.

In just a few days, I absorbed a great deal of knowledge.

The improvement from exercise was more noticeable; after just a few days of consistent morning exercise, my physical assessment score improved by '1' point.

[Body: 60.]

You passed!
The fact that the assessment results improved after just a few days of early morning exercise indicates that the body is indeed lacking exercise.

He could clearly feel that his physical strength had improved.

At first, I felt very tired after running a few laps in the morning, but now it's much easier, and I can even walk a few more laps without feeling particularly tired.

Correspondingly, I ate a bit more for breakfast.

Eating breakfast used to be a habit, but now it's become a necessity to replenish energy.

Friday, 1 PM is the time for a major course, "Theoretical Mechanics".

Theoretical Mechanics is the discipline that studies the fundamental laws governing the mechanical motion of objects, and mainly includes statics, kinematics, and dynamics.

This course was not difficult for Zhang Minghao.

But I still gained something from the class. For example, I met a few new classmates before class, one of whom was Ma Yan, who was also pursuing a doctorate under Xue Kun.

Ma Yan has a neat buzz cut, a slightly chubby figure, a square face, square-framed glasses, and a big belly, giving him a somewhat pampered air.

He is a very cheerful and outgoing person.

Upon hearing that Zhang Minghao's advisor was Xue Kun, he immediately sat down beside him, "We have the same advisor!" "But I've never seen you before? You didn't come to the last 'Mathematical Methods' class... Oh, right!"

"Teacher Yao said several things, you're the one who skipped class in the first period?"

Zhang Minghao nodded silently.

"Great!"

Ma Yan gave a thumbs up, "You dared to skip class in the first period, but I still don't recommend Professor Yao's class. That old man is really not to be trifled with; he's strict and has a bad temper..."

Zhang Minghao asked with a smile, "You know him?"

Ma Yan patted his chest forcefully, "I've been studying at Jiangnan University for seven years, and I know all the professors in the physics department."

He added, "There was one I didn't know, Xue Kun. I think he was a teacher who transferred from Donggang University, so I applied to him."

"I'm the exact opposite."

Zhang Minghao was only familiar with Xue Kun; he had only met the others a few times and could hardly be considered familiar with them.

"You know Xue Kun?"

"I did my postgraduate studies at Donggang University."

"They complement each other perfectly."

Zhang Minghao chatted with Ma Yan for a few minutes, and after class, they happened to go to find Xue Kun together.

Xue Kun was busy organizing the documents.

When he saw Zhang Minghao appear at the door, a flash of excitement appeared in his eyes. He stood up and waved, "Come in quickly!"

As he spoke, he even moved a chair over.

"sit!"

Only after he finished speaking did he notice the two people who had come in.

Ma Yan also came.

There were only two chairs in the small office, so he simply went to the room across the street and grabbed one.

Ma Yan leaned close to Zhang Minghao's ear and whispered, "Teacher Xue is so enthusiastic!"

Zhang Minghao nodded in agreement.

There were enough chairs, so the two of them sat down.

Xue Kun sat back down and started talking about what doctoral students should do after enrolling.

"You should pay more attention to the basic courses and read more materials and literature in your spare time."

"Doctoral students are different from graduate students; it's a new stage where academic talent is cultivated, and basic theoretical research and independent research capabilities are emphasized."

"The first year of doctoral studies is mainly for building a foundation. When you start your second year, you'll come to the lab and work on projects with me..."

These words were all spoken to Ma Yan, to tell him what he should do after enrolling in the doctoral program.

At the end, Xue Kun added, "Ma Yan, if you have any questions and can't find me, just ask Zhang Minghao."

"He can usually handle it."

Ma Yan was taken aback.

Before he could react, Xue Kun waved his hand outside, "Alright, that's enough for today, come again next Friday."

"You go first."

Ma Yan was momentarily confused. He looked at Xue Kun, then at Zhang Minghao.

He backed away from the room step by step.

Once he was in the hallway, something felt off. "What's going on?"

"Weren't we enrolled together?"

"Why do I feel like an outsider? And why should I ask him all the questions?"

"I'm a top student too!"
