Great Country Academician

In the storage room, Xu Chuan's eyes fell on the storage box that looked like a safe, and he looked at the carbon-based chips inside.

There are about a dozen glassware spread out on the cabinet floor.

It seems that this kind of finished carbon-based chip has been mass-produced at least on a small scale, otherwise there wouldn't be so many here.

After all, this is mainly for experimental testing, and generally speaking, the amount used will not be too much.

On the side, Zhao Guanggui carefully took out a glass box from the locker and handed it over.

Xu Chuan stretched out his hand to take it and looked at it.

At first, he thought the box holding the chip was a glass box. After taking it over, he realized that it was not glass, but a transparent plastic.

It may be polycarbonate or polymethylmethacrylate. It should be more resistant to buffering than glass. It is probably prepared to prevent accidental drops and damage to the chip inside.

His eyes fell on the thumbnail-sized black chip lying quietly in the card slot in the center of the container. Xu Chuan opened the box and took out the thumbnail-sized chip from inside.

Chips composed of carbon materials as the main body are also called carbon-based chips.

Compared with silicon-based chips, this type of chip has many advantages.

The electronic properties of carbon nanochips are more attractive than silicon. Electrons move more easily within carbon crystals than within silicon crystals, so they can have a faster transmission rate.

Professor Peng Lianmao from Peking University once explained: "Carbon-based semiconductors have the advantages of lower cost, lower power consumption, and higher efficiency."

"Compared to silicon-based semiconductors, carbon-based semiconductors are not only faster when processing big data, but also save at least 30% of power consumption."

Looking carefully at the carbon-based chip in his hand and feeling the fine and smooth texture, Xu Chuan couldn't help but sigh.

"it's beautiful."

This chip is very thin and light. It barely feels like it when held in the hand. It is boxy in shape and completely black. However, if you look closely with the naked eye, you can still see some faintly visible engraved textures on the surface of the chip.

Of course, when it comes to beauty, a pitch-black chip and a black square with few lines can hardly be said to be very beautiful.

But in the eyes of any researcher, this pitch-black chip shines brighter than diamonds and is more beautiful than gems.

After all, what is brewing in this small carbon-based chip is a future full of endless imagination.

Especially for China, this means that a technological breakthrough has been achieved in a field that has been stuck for a long time, which will bring huge potential for new industrial upgrades and economic benefits to the country.

If Silicon Valley is the catalyst for America's economic take-off, then the slowdown of Moore's Law is the fuse for the decline of silicon chips.

After all, silicon atoms have their own width limitations, and the tunneling effect caused by quantum mechanics will become more and more serious as transistors continue to shrink.

Although theoretically, the quantum tunneling effect of silicon-based chips can be reduced to about one nanometer, in fact, when the thickness of the logic circuit gate of the transistor in the silicon-based chip is less than seven nanometers, the quantum tunneling effect will occur.

And as the nanometer number gets lower, the tunneling effect becomes more severe.

With the development of technology, whether it is the quantum tunneling effect or the difficulty of photolithography, the future of silicon-based chips will be limited by the combined effects of various factors.

With development so far, the future upper limit of silicon-based chips can actually be seen.

But the progress of mankind will not stop. If silicon-based chips have an upper limit, then it is necessary to find products to replace them.

Carbon-based materials are one of the hottest future directions of previous research.

But the problem is how to accurately and stably arrange and control carbon materials such as 'carbon nanotube arrays' or 'graphene' to form carbon-based transistor integrated arrays. This is a problem that countries have not been able to solve.

It wasn't until they landed on the moon to develop the moon and accidentally collected rocks with natural carbon nanotube arrangements from the moon that they advanced this problem through nature. For Xu Chuan, although he does not know much about the semiconductor industry, he also knows that carbon-based chips are the "super chips" that allow China to catch up with Europe and the United States in this field.

The rapid development of the carbon-based semiconductor industry will be a key bargaining chip for them to become the world's number one in the chip field in the future.

After carefully looking at the pitch-black chip in his hand, Xu Chuan looked at Zhao Guanggui who was standing aside and said, "Tell me briefly about your results."

Zhao Guanggui nodded, cleared his throat and said, "I don't know much about the specific preparation technology of chips. After all, you know that I am not a researcher in this field."

"But I still know about the performance of this chip."

Although he is said to be in charge of the carbon-based chip project within Xinghai Research Institute, he is indeed not a scholar in the chip field.

However, as the project leader, he has been cooperating and liaising with Huawei HiSilicon, SMIC and other companies, and he still has some understanding of carbon-based chips.

After a pause, he continued: "Ambition HG05 is the name of this batch of prototype chips, also called Ambition 05."

"To put it simply, it is the seventh batch of experimental chips, which uses 28nm multiple exposure technology to integrate 10 million carbon-based transistors per square millimeter. Quad-core design, main frequency is 5.8Hz, thermal The design power consumption TDP is 30W.”

"In terms of performance, the Xiongxin 005 chip is benchmarked against Intel's Xeon series. From the current performance test, it is enough to reach the level of the high-end single-channel processor series E5-1600 series!"

"If it is replaced with the Intel Core I series that ordinary people are more exposed to, then it can reach the level of about the seventh generation, such as equivalent to i5 6300 or i7-5700"

In the simplest and most understandable way possible, Zhao Guanggui briefly introduced this chip.

For scholars engaged in academic research and scientific research, they are relatively more exposed to server-type computers.

Of course, ordinary computers are certainly often used, but for China, chip research and development, the priority is to ensure various types of "special" chips.

Although commercial carbon-based chips are already under development, their progress is indeed slower than that of server-type chips.

Listening to Zhao Guanggui's introduction, Xu Chuan nodded with satisfaction.

According to Zhao Guanggui, Xiongxin 05 can be compared to the level of Intel Core i5 sixth generation or i7 fifth generation, which is already very good.

Take Intel's i7 series for example. The earliest Core i7 processors used 45nm technology, while some subsequent models used 14nm technology.

If it is i7-5700hp, it uses 14nm lithography technology. When put into the chip, it belongs to the mid-to-high-end level and is one of Intel's 5th generation series products.

Although the number of carbon-based transistors integrated per square millimeter is only 10 million, for this initial sample, it is still in the stage of further improving the performance of the original product to achieve this level, he is already very satisfied.

Although he is not very clear about the specific integration of transistors per square millimeter in Intel's i7-5700hp processor chip, according to the information he has checked before, it should be around 30-50 million.

With the number of 10 million carbon transistors per square millimeter of carbon-based chips, it can achieve the same effect, which is already very good.

Of course, carbon-based chips and silicon-based chips are two different types of products.

Especially in terms of frequency, even if there are only tens of millions of carbon-based chips per square millimeter, the main frequency is far higher than the benchmark silicon-based chips.

If he remembers correctly, Intel's fifth-generation I7 should have a main frequency of only about 3.3Hz, while the main frequency of Xiongxin 05 has reached an astonishing 5.8Hz, which is 1.75 times higher.

In terms of energy consumption, compared with Intel's fifth-generation I7 47W·TDP power consumption, Xiongxin 05 only has 30W·TDP.

It is already very excellent for the first-generation product to achieve this level.
