Transistors are the main electronic components that are used as amplifiers in analog circuits or electronic switches in digital circuits . And their development is the main key to nanoelectronics in the field of production and monopoly (nanochips) in the field of military and biological industries. Transistors and integrated circuit fabrication technology have become the most common basis for them, CMOS technology in the micro and nanoelectronics industry. This industry and technology of integrated circuits, this advantage of nanoelectronics in reducing the size of transistors and the number of transistors used in each chip is doubled. Reducing the dimensions of the transistors increases the speed and reduces the power losses.
The simple basic structure in which the two metal joints act as a source and drain and carbon nanotubes play the role of a transistor channel that is separated by a layer of oxide from a high-density silicon shell. In this electronic component, the silicon substrate acts as a gate. In this structure, it is called the back gate . Then the high gate transistors, which were suitable for use in integrated circuits , with the addition of an upper gate separated by a thin layer of oxide from the nanotube channel, the transistors are the same as transistors based on carbon nanotubes. The difference is that graphene is used in its channel instead of carbon nanotubes. Unique properties of nano-graphene such as electron mobility and high thermal conductivity, failure resistance, Properly absorbs low light and gaps that make it possible to make high-speed electronic components in flexible and transparent electronic circuits using this nanomaterial. Graphene nanotransistors, in terms of structure, can have different types of back and hybrid gates (upper and lower). Combined gates (Not; or; And; Nand) are made by nanotransistors.
The design , manufacture, development, and use of products ranging in size from 1 nm to 100 nm are called nanoelectronics. In fact, we are talking about miniaturization, which makes it possible to have more contact, more activity and increase the area. Nano is a new scale in technology and a new approach in all fields, and it gives human beings the ability to expand their involvement in the structure of materials and to design and manufacture in very small dimensions, and in all technologies. That human beings have already achieved . And this trend has been considered in the production of electronic and biological nanotechnology. Implantable nanochips in the body and the military industry depend on advances in carbon nanotransistors and graphene.
Conclusion :
Nanotube-based graphene nanotransistors and carbon-based nanotransistors are very serious candidates to replace conventional silicon transistors.
