Recently, the MIT (MIT) researchers found that graphene technology can make the chip one million times the rate of ascension. Former MIT Dr. Ido Kaminer, said the technology in the process of transfer and store data, can make the computing power of the chip to a very high level.

In the past few decades, silicon has been manufacturing the raw material of choice for chip. Silicon chip itself, however, there are many defects, silicon material that is lack of room for improvement in terms of chip manufacturing. With the gradual development of graphene technology, the chip industry also faces an innovation. Many researchers hope the graphene technology is applied to the chip, many enterprises is also investing in research and development of the technology.

Graphene technology more mature may bring huge change for chip industry. However, in this process, also will still face some inevitable defects.

Graphene technology is a little more popular Chip industry in the future or innovation

A, graphene technology advantages, the future or main material into a chip

Graphene is a structure composed of carbon atoms in single chip of new material and its thickness is only equivalent to a carbon atom. Graphene is arguably the world's most thin is the most hard materials, and minimum resistivity materials in the world.

Due to the above properties, graphene has become a kind of good conductors, can be used to make plate, solar cells and transparent touch screen with high-tech products. Also can carry on the electronic noise reduction, gene sequencing, etc.

The MIT that graphene can make fast rate of chips, is also due to the nature of the graphene.

The characteristics of the MIT researchers found that graphene can reduce the rate of light, resulting in a dense beam. Because of this phenomenon and the aircraft beyond "sonic" generated when the speed of sound similar, so called "light".

In the process of smooth blasting, when the speed of movement is limited because of fast light, the electrons in graphene can release "plasmons", this phenomenon can be developed for the light of ultra-thin computer equipment base circuit ground.

As is known to all, traditional raw materials mainly silicon chip. However, graphene is much more useful than silicon.

Made of silicon chip, the structure is single, by wire connection between them. Chip in the large flow of data, such as distance data, tend to spend more resources, and frequent clogging.

Graphene is different, it is hexagonal, honeycomb lattice type of thin film, excellent conductivity. So can fast data transmission and improve chip rate.

In addition, the frequency of silicon-based materials chip is proportional to the heat, and the frequency and chip performance is one of the important measures. As a result, many manufacturers in order to control the heating problem will take some frequency reduction measures.

At present, the silicon chip the highest frequency of 8.4 GHz in liquid nitrogen environment, PC processor frequency for 3-4 GHz, mobile processor frequency is around 2 GHz. If to use in the manufacture of chips, graphene materials effect will be much better.

Compared with silicon-based materials, graphene carrier mobility at room temperature can reach more than 10 times of silicon, can reach 100 times in the laboratory environment, saturated speed can be up to 5 times of silicon at the same time. Due to the thermal conductivity of the graphene is good, in theory can make the chip frequency up to 300 GHZ, and power consumption is lower than the silicon chips.

For graphene technology role in the study of the chip, at least able to identify two points.

First, the graphene material relative to silicon-based materials with better properties, speed, power consumption and can reduce performance. Graphene technology can be pushed into the technology of the 8 nm even 5 nm node, this is the digital circuit after 2020 goals.

Second, graphene is applied to the chip of the scheme is feasible. In the laboratory, many researchers have developed the technology, into practice is just around the corner.

In fact, graphene technology at present also attaches great importance to by the parties.

Second, the graphene technology favor by the parties, or change the chip industry

Because the graphene technology has many advantages, many technology companies have begun to research and development on the chip application.

IBM is a giant in the field of hardware, but in recent years, the situation of the whole hardware industry decline, innovation become the key. So IBM is constantly trying to new technologies, in order to reverse the unfavorable situation caused by hardware industry declined, and the key of innovation, is the technology of graphene.

IBM's main plan is to improve chip performance and reduce its size, so as to promote efficiency of the chip. For just the graphene technology can meet these requirements, IBM has invested $3 billion, try to innovation of chip, realizes the hardware business recovery.

The is Group, a research director Richard Doherty believes that many power flow through The silicon chip is turned into heat, so The speed of The silicon chip is hard to have rise of space. IBM has said that graphene materials of electronic migration velocity is 10 times of silicon materials. In the future, they will more study for this field.

In addition, huawei also has carried on the graphene investment in the UK. As one of the few in the domestic mobile phone manufacturers have their own chip companies, graphene technology will become the key research object. , senior vice President of huawei lliillyy fang said: "we will cooperation in the field of graphene, information and communications industry for the future development, build a better world all connection, provide important fundamental support."

In our country, puts a premium on graphene technology also. A few months ago, the national development and reform commission, ministry of industry and the ministry of science and technology three ministries issued "about accelerating the development of graphene industry innovation several opinions, designed to guide the graphene industry innovation, cultivating graphene industry grows further, and promote the innovation of material industry finally.

Is so importance to graphene technology in our country, because of its high speed of carrier, scattering limited, narrow excellent geometric features, making it a material of choice for electronic devices and integrated circuit. In addition to the chip industry, graphene can also in optical fiber communication technology, the sensor manufacturing, 5 g in the field of communications and other important applications.

However, graphene technology also has some limitations.

First, the high cost of graphene.

Graphene's highest price reached 5000 yuan/grams, in the industry is called "black gold". Therefore, general enterprise to research and development in terms of money, which is why the graphene technology players are basically giants such as samsung, IBM, Intel's important reasons.

Second, graphene techniques have limitations.

The growth of graphene is strict control condition, must make a reservation on the insulating substrate, to grow out of the required diameter size of semiconductor graphene. But to strictly control the growth of the graphene conditions it is impossible.

Third, unable to achieve large-scale application.

Due to high cost and technical limitations, the production of graphene is still at the experimental research stage, did not realize large-scale production in commercial use. Silicon-based materials, by contrast, still has advantages in terms of cost and stability.

In fact, the combination is also a good choice. Previously, Columbia University, has been the development of a graphene - silicon photoelectric hybrid chip. Applied physics professor Philip Kim believes that the combination of the two materials have ultrafast nonlinear optical modulation performance, this will be for chip, integrated circuit, high speed optical communication, and other fields to open the new door.

With the development of the mobile end, PC gradually decline. If we can develop faster chips, will make faster computing power into a reality. It can not only promote the progress of the chip industry, but also can promote the development of artificial intelligence and cognitive computing. Although the graphene technology still exist, but in the future, this technology may bring chips and related industry a revolutionary change.
