Norwegian low-cost method for producing graphene on semiconductors
According to a report by the Daily Science Network on September 11, researchers at the Norwegian University of Science and Technology have developed a low-cost method for growing graphene on gallium arsenide nanowires. The researchers said that this graphene semiconductor hybrid material has excellent optoelectronic properties and transparency, flexibility and other characteristics, is expected to accelerate the commercialization of graphene, bringing changes to the semiconductor industry. Related papers were published in the journal Nano Express. Professor Herge Weiman, professor of electronics and telecommunications at the Norwegian University of Science and Technology, who is in charge of the research, said: "We have not seen it as a new product, but as a new way of manufacturing semiconductor devices. It is expected to be the basis for the manufacture of new electronic devices. His team has made a transparent, flexible, flexible electrode by this method. Graphene is a new material with a single-layer sheet structure composed of carbon atoms. It has extraordinary conductivity, better strength than steel and excellent light transmission. Many people think that its appearance will be The field of modern electronic technology has triggered a revolution. Companies such as IBM and Samsung have been looking for alternatives to silicon to produce more efficient and lightweight electronic devices. New technologies will help them break through existing design constraints and create devices such as flexible touch screens. Researchers say the new technology can be applied to most manufacturers' existing production equipment without having to replace the entire production line. Researchers say the new technology is likely to be used first in the manufacture of new solar cells and light-emitting diodes. It will hopefully become the platform for future electronic and optoelectronic devices. Solar cells made with nanowire technology will have high efficiency, flexibility and low cost, and will have a very broad application prospect. According to this technology, self-powered nanomachines and 3D integrated circuits made of graphene and nano-semiconductor wires are also manufactured, making electronic devices with smaller and better performance a reality. In addition, Weiman said that this technology can also be used to make self-powered consumer electronics products, which will appear in various corners of life, from clothing to scratchpads. Of course, there are fewer common devices such as mobile phones and tablets. . He said that the technology for growing graphene on semiconductors is expected to become the basis for the manufacture of new electronic devices, which will further accelerate the practical and commercialization of graphene, making it faster to enter the lives of ordinary people.
