  Application


The semiconductor industry, the photovoltaic industry, lithium-ion battery, aerospace, military, and other next-generation display



First, the electronics industry
 
1, instead of silicon production supercomputer: Scientists have discovered that graphene is the best known conductivity material. This feature is particularly suitable for graphene frequency circuit. Frequency circuit is a leader in the modern electronics industry, some electronic devices, such as mobile phones, since engineers are seeking to fill more and more information in the signal, they are required to use higher and higher frequencies, however, the phone's work the higher the frequency, the higher the heat, so the high frequency boost will be severely limited. Since the emergence of graphene, the development prospects of high-frequency boost seems to have become infinitely large. This makes it in the field of microelectronics also has great potential. They even considered graphene silicon substitute, it can be used to produce future supercomputers.
 
2, microelectronics: microelectronics technology is high-tech and information industry's core technology. The microelectronics industry is a basic industry, the reason for developing so fast, in addition to the technology itself enormous contribution to the national economy, and it is also highly related to permeability. With the development of integrated circuit technology, the machine, with clear boundaries circuit element, between devices is suddenly lame, device problems, electrical problems and the whole system has problems together, reflected in a small piece of silicon, This forms a solid state physics, electronics device technology and new technology of the three cross a microelectronics discipline. But with the development of microelectronics, the new limit is also apparent, as the new material graphene offers the possibility to solve this limit, and graphene chips have been manufactured out, the only need is to break through industrialization, as long as this issue is resolved it will usher in a new computer revolution.
 
3, graphene phone: Posted graphene phone, apparently have been released graphene industrial application of the tide coming signal to the market. Business layout graphene and other cutting-edge materials, will soon become Kangdexin new growth point. In addition, as Kant new polymer composites platform company, has formed an optical film and laminating film two major industrial clusters, so the main line to the new material, graphene and other sophisticated layout in the field so that new prospects Kant even more exciting.
 
4, the high sensitivity of the sensor: graphene has a larger surface area, it has a high sensitivity of the sensor production conditions, once the gas is adsorbed on the graphene surface, the surface resistance will change, and then combined with electrical sensor detector , it can make graphene becomes an excellent gas sensor.
 
5, the photon sensor: graphene photon sensor may face appears on the larger market for detecting optical fiber carries information. Now, this role is filled by silicon, but silicon era seems to come to an end. Last October, IBM's first disclosure of a research team developed their graphene photodetector ..
 
6, molecular-level electronic circuit: Researchers at the University of Manchester, United States of America made with graphene and molecular electronics. Graphene can be carved into a single transistor has an electronic circuit, the smaller number of large molecular size than the transistor size, the stronger its function. The researchers also said that from the graphite oxide to graphene West simple conversion is an important way of producing a conductive nanowires, which not only can be used in flexible electronics field, and is also expected to be used to produce bio-compatible graphene wires can be an electronic signal is used to measure a single biological cell.


Second, the photovoltaic industry
 
1, a new generation of solar cells: one instance of the application of graphene were high hopes that a new generation of very high conversion efficiency of solar cells. Looking to its future applications, the first field is a transparent conductive film, followed by the middle of the field electrodes. Because only in place of graphene or a flexible high performance ITO aspect, graphene and only the transparent conductive film for a solar cell can be achieved is a very important feature. This feature is for all infrared include infrared COSCO, including high transparency. While infrared energy occupy a considerable part of the solar radiation, but most of the existing solar cells are unable to infrared energy source as effectively. This is because in addition to the effective photoelectric conversion itself is not easy to achieve, so far used for transparent electrodes of ITO and FTO infrared transmittance actually relatively low. If you only want to ensure transparency in the infrared is sufficient, then the development of the material is not difficult. However, most of this material will face significantly lower conductivity problem in principle. Graphene is almost the only material capable of avoiding this problem. The reason is that the graphene with a very high carrier mobility. Therefore, even if the carrier density is very small, but also to ensure a certain degree of conductivity. This material is very rare. Recently, some research institutions are actively developing the photoelectric conversion layer material, some of the infrared efficient conversion technologies also have been published. That way, if you can take advantage of higher transparency to infrared transparent conductive film, then you can expect to achieve far more than the conventional solar cell conversion efficiency.
 
2, the transparent electrode: at the end of October graphene Innovation Conference held in Qingdao on Hongbing Xi said graphene transparent electrodes have been widely used in a variety of flexible photovoltaic device includes a touch screen sensor, an organic light emitting diode (OLED) and organic photovoltaic devices.



Third, the semiconductor industry
 
1, the electronic wire: a US joint research team said they were using graphene produce nano-circuit the field to get a breakthrough: to design a simple, fast nano wire manufacturing method capable of tuning graphene chemical characteristics make graphene oxide from insulating substance becomes a conductive substance. This was identified as a graphene electronics in the field of key findings related to the study published in the June 11 issue of "Science." Members of the reason for the study of nano-circuit graphene considerable enthusiasm, because, unlike silicon, electrons in graphene will be less resistance when moving, and the size of silicon transistors has also been close to the people related to the laws of physics research limit. While graphene nanoelectronics comparable silicon-based electronics faster and consume less energy, but had no one knows how to make reusable or scalable graphene nanostructures.


2, the new battery energy:
new energy battery is graphene one of the important areas of the earliest commercial. Before the Massachusetts Institute has successfully developed a surface with nano-graphene layer flexible solar panels, can greatly reduce the manufacturing transparent deformable cost of solar cells, this battery is possible night-vision goggles, cameras and other small application of digital devices. In addition, the successful development of super-graphene battery, but also solves the problem of new energy vehicles battery capacity and long charging time of the issue, which greatly accelerated the development of new energy battery industry. This series of research results is graphene in the new energy battery industry paved the way for the application.
 
3, lithium ion battery: According to the Chinese Academy of Sciences researcher metal Huiming introduced in the field of clean energy, graphene application prospects. The biggest problem is the stability of clean energy and mobile storage challenges. The main storage for the super capacitor and battery, are required to meet the high energy density, high power density, high reliability and long life. Conductive graphene increase the lithium electrode. They graphene mixture used in lithium battery, the mileage can be increased to more than 400 kilometers.



Fourth, the new generation of monitors
 
1, the liquid crystal display material: from an optical standpoint, graphene is a "transparent" conductor, can be used to replace the current LCD material. The current liquid crystal display is based on the use of indium-based metal oxide film, and the metal indium is very rare, in the next decade is expected to occur in short supply. In addition, compared with the current key raw material silicon computers, mobile phones and other electronic products, graphene also has many advantages, it is expected to replace silicon in the future, it is widely used in electronics production.


2, flexible screen: a bendable screen high-profile CES, the future development trend of mobile device display. Flexible display future broad market prospects as graphene base material is also good. Data show that in 2013 the global demand for mobile phone touch screen in about 965 million. By 2015, demand for large-size tablet touchscreen will reach 230 million, graphene applications provide a broad market. Samsung researchers have also been produced by the transparent multi-graphene material composition bendable display, I believe that large-scale commercial just around the corner.



V. aerospace. Military
 1, due to the high conductivity, high strength, ultra-thin and other characteristics, graphene application advantages in the field of aerospace industry is also very prominent. Not long ago, the United States applied to NASA to develop aerospace graphene sensors, can be good for trace elements in the Earth's upper atmosphere, the spacecraft structural defects can be detected. The potential applications of graphene on ultralight materials will also play a more important role.
