Chapter 848: Dazzling diamonds

The carbon-based chip is complete!
This is probably the best news that Lu Zhou has heard in the past few days.
After being surprised for a while, he didn't hesitate and immediately asked Yang Xu to take himself to the Institute of Computing Materials and find the laboratory where the carbon-based chip project team is located.
When the two arrived at the laboratory, the laboratory was quite quiet.
A group of researchers at the hairline were surrounded by a laboratory equipment about two people tall, and one of them was carefully debugging something.
Without going up to disturb them, Lu Zhou pulled Yang Xu and waited at the door for a while.
Soon, the sound of astonishment spread from the crowd.
Looking at the excited expressions on the researchers' faces, Lu Zhou could guess without asking, they should have discovered something extraordinary.
Waiting a little, Yang Xu looked at Lu Zhoudao.
"Let's go."
Lu Zhou nodded.
"Ok."
Bypassing a lot of experimental equipment and walking into the laboratory, when the two were close to the experimental equipment, the group of researchers finally found Lu Zhou and Yang Xu.
Standing in the crowd, a middle-aged man who looked very academic, with a surprised expression on his face, hurried forward.
"Director Yang? Dean Lu?"
"This is the person in charge of the project," knowing that Lu Zhou met this for the first time, Yang Xu introduced him skillfully, "Professor Wu Tianqun."
"Hello Professor Wu."
"Hello, hello," holding the right hand of Lu Zhou in astonishment, Professor Wu shook enthusiastically. "Academician Lu, why are you here in person?"
"I heard that the experiment was fruitful, Yang Xu pulled me over," he released his hand and looked at the device in the crowd. Lu Zhou asked with a smile, "Is it done?"
The lumbar plate was very straight, Professor Wu said with a red face.
"This is a repeated experiment. The first experiment was successful yesterday!"
Lu Zhou said immediately: "Will you show me something?"
Professor Wu immediately made a please gesture.
"Please follow me!"
Production of a chip is a quite complicated thing. With a silicon wafer as the substrate, a layer of photomasks are stacked on top of each other, and stacked like a Lego toy, and finally a complete chip can be obtained.
This may sound easy, but considering that these "toys" are all in the nanometer size, and that it also includes complex IC designs and photolithography processes, etc., which is a technology that is clouding in the mouth, Whether it is possible to produce a chip that meets market expectations has almost become an important indicator of the basis of a country's electronics industry.
Not to mention what this means for a country or an enterprise, just discuss this issue from a technical perspective.
In the CMOS process, the characteristic size is typically represented by the width of the "gate", that is, the channel length of the MOS device. In general, the smaller the feature size, the higher the chip's integration, the better the performance, and the lower the power consumption.
However, this size cannot be reduced indefinitely.
First, the silicon atom has its own width, and then the tunneling effect in quantum mechanics will become more and more negligible as the line width continues to shrink. The combination of various factors will severely limit the future of silicon-based chips. .
However, human pursuit of new technology is eternal.
Since silicon-based chips aren't working, we can open up new battlefields on other materials that may work.
According to the latest research, the use of carbon nanotubes and molybdenum disulfide and other materials has opened a new way for the chip manufacturing process to continue to improve, allowing people to see the dawn of continuing Moore's Law.
However, the situation is not always so optimistic.
Although these two materials have the potential to replace silicon-based chips, but because of their respective shortcomings, research institutions worldwide who have studied silicon-based chip replacement materials have been unable to break through the most critical bottleneck.
That is, using these two groundbreaking materials, the core component of the chip—the transistor!
As early as when studying graphene superconducting materials, Lu Zhou discovered that two sheets of single-layer graphene that overlap at a special angle will show the characteristics of Mott insulators under special circumstances.
This major discovery not only directly led to the explosive breakthrough of later carbon-based superconducting materials, but also laid the foundation for the success of Pangu's controllable fusion reactor.
Not only that, but Lu Zhou was keenly aware that this feature could not only be applied to the superconducting field, but would also play an unexpected role in the semiconductor field.
Of course, he did not know the semiconductor industry well, but made such judgments out of academic intuition.
At that time, he originally planned to pull the partner's manager, Baosheng Group, to invest in the project together, but unfortunately, at the time, manager Sun felt that the project was not very reliable. As a manager of the subsidiary of China Airlines Group, he was not that big Decision-making power, so Tai Chi was eliminated.
However, Lu Zhou did not care. One was not short of money, the second was not short of people, and the third was not concerned about losses. After returning to China, he pulled a research and development team by himself and hung it under the Institute of Computing Materials. Up.
It has been two or three years since the project was established, and finally I have seen the dawn of dawn.
Standing next to the experimental equipment, looking at the transistor completed by the carbon-based chip project team through a microscope, after a long time Lu Zhou couldn't help but sigh with emotion.
"Pretty……"
Although its raw material is dark graphite, it is peeled into graphene fragments and stacked into layers. It is like a finely crafted diamond, exuding a brilliance in the image presented by the microscope.
Standing next to him, Yang Xu couldn't help but saw Lu Zhou remove his eyes from the eyepiece and quickly stepped forward.
"Let me see too."
Lu Zhou smiled and stepped aside, giving up the eyepiece to Yang Xu.
After looking into the eyepiece for a while, it took about two minutes before he let out a sigh of emotion ~ EbookFREE.me ~ Describe it with diamonds is really worth it ... I dare say that all the diamonds in this world add up, Nothing is more valuable than this thing. "
Lu Zhou laughed.
"That's too exaggerated ... but I agree with you that using diamonds to describe it is indeed a bit cheaper."
If it sells the gadget to the auction, even if it shouts a sky-high price to buy a whole car diamond, there will be a large group of people willing to pay for it.
after all……
In this small carbon-based transistor, the future is full of imagination ...
Looking back at the researchers standing behind him, Lu Zhou cleared his throat and said.
"As long as carbon-based transistors can be manufactured, it is equivalent to breaking through the most critical bottleneck of carbon-based chip technology! Although the size of our carbon-based transistor is still an order of magnitude behind the size of common silicon-based transistors on the market, Chips made of transistors, in the theoretical minimum process, are unthinkable for silicon-based chips! "
Just how unimaginable it is that Lu Zhou is difficult to describe in words.
The only thing that is certain is that this great research result has broadened the lower limit of the chip process by an order of magnitude!
It is no exaggeration to say that if Professor Wu intends to evaluate the academician, with this result, he will be able to find a way to push him as soon as the next academician's additional election year comes to Lu Zhou.
Even if it doesn't work, it will definitely work again!
"Your job is excellent!"
Looking at the group of excited researchers, and Professor Wu Tianqun, who was full of excitement and pride, Lu Zhou paused for a moment, and continued with solemn tone.
"Just today, just now, we made history and redefine the future!"
