Chip Research Institute!

Ye Fei has been coming to the Chip Research Institute for a week, and the basic situation has been understood.

The research of the chip research institute is still in the earliest stage, that is, the micro-size manufacturing technology.

There are three major challenges in graphene chip research, namely micro-size manufacturing technology, spare parts quality and relative life.

At present, graphene chips are manufactured using ordinary chemical vapor deposition technology, but it is difficult to prepare smaller graphene single crystals with this technology.

A single crystal is a graphene crystal.

For example, 5nm graphene chips, single crystals are 5nm graphene crystals.

Now, the Chip Research Institute is going to develop a technology that can prepare smaller graphene single crystals.

Smaller graphene single crystals can improve the performance of graphene crystals.

For example, graphene chips, 5nm graphene chips have higher performance than 7nm graphene chips.

In the lab!

Ye Fei sat in front of the electron microscope and observed the structure of the graphene that had just been configured.

Ye Fei will change the angle of graphene with different layers, thus changing the internal structure.

He wanted to find a simple and convenient graphene preparation technology by observing the internal structure.

At the same time, according to the fullerene fusion method developed by himself, Ye Fei also fused graphene with graphene in different layers to see what strange discoveries would be made.

"Huh?" Ye Fei suddenly wondered: "The space between the 1.1-degree angle of the single layer and the 0.67-degree angle of the double layer seems to be a bit special. ”

As he spoke, Ye Fei carefully observed the space at this range angle.

"Wait!" Ye Fei exclaimed in his heart: "What is this?" ”

"The purity of this crystal seems to be a little different."

Ye Fei found a very special graphene crystal in the space between the 1.1 degree angle of the single layer and the 0.67 degree angle of the double layer.

"It seems that this graphene crystal is very pure!"

"Xiao Wu!" Ye Fei shouted without raising his head.

"Director!" A young man who was doing an experiment looked up at Ye Fei and asked, "What's the matter?" ”

Ye Fei said: "You turned on the detector and tested the purity of this graphene crystal I observed." ”

Xiao Wu said in surprise: "Director, have you found anything?" ”

"Don't talk nonsense!"

When Xiao Wu heard Ye Fei's words, he knew that Ye Fei must have found something, so he was excited and hurriedly went to turn on the detector.

The rest of the people in the laboratory didn't bother to do experiments, so they followed to see Xiao Wu's operation.

Soon, on the computer screen of the detector, the purity of the graphene crystals that Ye Fei was observing was displayed.

Ye Feidao: "What is the purity of the graphene crystal that I am observing now?" ”

The eyes of the people who were looking at the computer screen widened in surprise.

Ye Fei didn't hear the voice, he looked up at Xiao Wu and the others: "Xiao Wu, speak!" ”

Xiao Wu woke up like a dream, turned his head to look at Ye Fei, and said in a daze: "Director, it's 98.3%." ”

"What?" Ye Fei stood up in shock and walked to the detector, looking at the computer screen, which showed 98.3%. ”

The purest graphene crystal in the world is 99.5%.

However, the purity of 99.5% graphene crystals is artificially purified.

The 99.5% graphene crystal purification technology is in the hands of Beili Kingdom.

The purity of graphene crystals in nature has no lower limit for the low, and the highest is about 95%.

Ye Fei now found 98.3% graphene crystal purity.

That is to say, there is no need for purification, and it beats the graphene crystal purification technology of 99% of countries.

If purified at a later stage, the purity of graphene crystals may exceed 99.5%.

Xiao Wu looked at Ye Fei in surprise and asked, "Director, how did you do it?" ”

The rest of the people also looked at Ye Fei with shocked faces.

Ye Fei shook his head and didn't speak, looking at everyone: "Don't say this, you know the consequences if you say it." ”

The crowd nodded hurriedly, they knew the importance of this matter, and no one would have good fruit to eat if they said it.

may have been arrested before he got out of the graphene research institute.

Ye Fei said: "You continue the experiment, I'll go to the dean." ”

"Also, no one should move where I was just sitting, ten meters away from it."

The crowd nodded.

Ye Fei was still not at ease, so he walked back to the electron microscope he was sitting on and destroyed the graphene crystals under the electron microscope.

After that, Ye Fei walked out of the laboratory with confidence and went to find the dean.

Dean's Office!

Ye Fei knocked on the door, and walked in after hearing a voice to please come in.

The dean is talking with Director Gao, director of the Fullerene Research Institute.

The dean said to Ye Fei: "Wait a minute." ”

Ye Fei nodded, and then sat down on the sofa.

Soon, after the two finished talking, Director Gao stood up and smiled at Ye Fei: "Director Ye, have time to drink tea with me." ”

"Okay!" Ye Fei said with a smile.

After Director Gao left, Ye Fei sat opposite the dean and said, "Dean, there is a major breakthrough in graphene chips." ”

"Huh?" The dean said in surprise: "You've only been there for less than a month, right?" ”

Ye Fei said: "When I was experimenting just now, I found that a graphene crystal that has not been purified in nature has a purity of 98.3%. ”

"Oh, 98.3%!" The dean smiled: "Isn't it 98.3%?" ”

"Wait?" The dean was suddenly stunned and said, "How much do you say?" ”

“98.3%！” Ye Feidao.

"Nature, unpurified graphene crystals?" The dean asked.

"Hmm!" Ye Fei nodded: "Yes!" ”

The dean gasped, then stood up in surprise and said, "Let's go, take me to have a look." ”

"Okay!"

After speaking, the two walked out of the office quickly and walked towards the chip research institute.

The dean was very excited, and sure enough, it was right to find Ye Fei, and it was only less than a month before there was a breakthrough.

Discover the purest graphene crystals in nature.

Such crystals, if purified casually, can make the purity exceed 99.5%.

Xia Guo's graphene crystal purification technology is not good, but it is found that graphene crystals with high purity can also obtain graphene crystals with 99.5% purity.

It doesn't matter if it's a black cat or a white cat, the one that can catch a mouse is a good cat.

The dean said in his heart: "If Lao Zhang is still here, he will not be able to achieve this achievement in his life." ”

Director Zhang of the Logistics Department: "......"

Ten minutes later, they entered the chip research institute, and Ye Fei took the dean into the laboratory.

When the people in the laboratory saw the dean coming, they all stopped what they were doing and looked at the dean and Ye Fei.

Ye Fei sat down in front of the electron microscope and said, "Dean, the graphene crystal I found was destroyed by me, and I will reprepare it for you now." ”

"Good!" The Dean nodded.

Half an hour later, Ye Fei reprepared the high-purity graphene crystal, which was then displayed on the detector's display.

After that, Ye Fei stood up from the electron microscope and said, "Dean, look." ”

The dean first glanced at the data on the detector's display, and then sat down in front of the electron microscope to look at the graphene crystals prepared by Ye Fei.

After a while, the dean stood up and said excitedly: "Very good, sure enough, it is a graphene crystal with a purity of 98.3%. ”

"You write out the report, and I'm going to notify it."

"Good!" Ye Feidao.

Two days later, Ye Fei wrote out the report, and the dean began to notify it.

The above attaches great importance to this matter, and personally sent a team of experts to check, and after inspection, it was found that it was indeed a graphene crystal with a purity of 98.3%.

The team of experts sent above is led by the director of the Xia Academy of Sciences, the dean of the Xia Guo Materials Research Center, the academician of the Xia Guo Materials Institute, and Academician Huang Xiuming.

After viewing, everyone entered the conference room and sat down.

Academician Huang looked at Ye Fei with a smile and said, "Academician Ye, it's not simple, you can make such a major discovery." ”

"If the news gets out, the whole world will be hotly discussed."

With the importance of graphene, Ye Fei's discovery can be said to have shocked the world.

With such a high purity graphene crystal, a higher purity graphene crystal can be obtained after being purified casually.

If there is a good purification technology, the purity of graphene crystals can be higher.

It is possible to get infinitely closer to 100% purity.

The purer the graphene crystals, the better the properties of the things used to make them.

Everyone knows that the smaller the chip, the better the performance.

The higher the purity of graphene crystals, the better the performance.

Of course, if the size is smaller, the graphene crystal performance will also be better.

However, performance is a combination of combinations.

For example, a graphene crystal with a purity of 99.5% performs better than a graphene crystal at 7nm.

The graphene crystal performance of 5nm is better than that of graphene crystal performance of 99.5% purity.

99% purity 7nm graphene crystal, better performance than 99.5% purity graphene crystal and 5nm graphene crystal.

Therefore, although Xia Guo has not yet developed a good micro-size manufacturing technology.

However, it can have high-purity graphene crystals, and it can also improve the performance of graphene crystals.

Ye Fei heard Academician Huang's words, smiled and didn't speak.

Academician Huang said: "We have seen your findings, and it is indeed 98.3% graphene crystals that have not been purified in nature. ”

"As for how pure graphene crystals will be purified, we don't yet know."

"But in my estimation, it could be purified to 99.7% purity."

Graphene crystals with a purity of more than 99% have a leapfrog improvement in performance for every 0.1% increase in purity.

Don't look at the purity of 99.7% and 99.5%, in fact, there is a big difference.

As for 100% pure graphene crystals, that's just a dream to exist.

If 100% pure graphene crystals appear, then the performance is much higher than that of 99.9% pure graphene crystals.

The two can be said not to be of the same rank.

When everyone heard Academician Huang's words, they were very excited.

99.7% purity!

I couldn't have thought of it before.

Academician Huang said: "Academician Ye, the Academy of Sciences will purify the graphene crystals you found, and after purification, the results will be told to you as soon as possible." ”

The best graphene crystal purification technology in Xia Guo is in the hands of the Academy of Sciences.

Ye Fei nodded.

"Also, after purification, the Academy of Sciences will announce the news, and you also know that my country has always been weak in chips."

"At this time, the news will be announced, which can boost the confidence of the Chinese people and increase their international status."

Ye Fei nodded, he understood this truth.

In the field of chips, Xia Guo has always been weak.

When there is good news, it is good for both the people and the country to announce it.

"So, when the news is announced, your name will be on it, and you have to be mentally prepared."

Ye Fei said: "I know! ”

"Graphene crystal purity, you have to continue to research, maybe you can find higher purity graphene crystals!" Academician Huang jokingly said.

He knew that the purity was already so high, and there should be no more pure graphene crystals to be found.

The rest of the people also smiled, knowing that Academician Huang was joking.

However, Ye Fei took it seriously, Ye Fei said seriously: "I will, if I can find a higher purity graphene crystal, I will notify you to come and test it." ”

"Uh......" Academician Huang saw that Ye Fei was serious, and he nodded and said, "Okay, you keep working hard!" ”

Academician Huang shook his head in his heart and said, "This kid is too simple. ”

After the meeting, Academician Huang and others left the Graphene Research Institute.

Half a month later!

The Academy of Sciences announced a message to the public.

[Academician of Zhonghu University, Academician Ye Fei, found graphene crystals with a purity of 98.3% in the Graphene Research Institute.

After purification by the Academy of Sciences, the purity of the graphene crystal reached 99.7%. 】

Soon after the news was released, it attracted the attention of countries and people in the know.

Many ordinary people don't know what this news means.

But those who know know that this news can be said to shock the entire graphene circle for the graphene industry.

And for Xia Guo, it can be described in one sentence.

The chip field is expected to achieve corner overtaking!
