Note: A simple basic structure that plays the role of a source and a carbon transducer in two metal joints, which is separated by a layer of oxide from a high-density silicon shell. In this nano-electronic component, the nano-silicon substrate acts as a gate, which in this structure is called the back gate .
Then, high-gate nanotransistors that were suitable for use in integrated circuits , with the addition of an upper gate that is separated from the nanotube channel by a thin layer of oxide, are graphene nanotransistors similar to carbon nanotube-based transistors. With the difference that graphene is used in its channel instead of carbon nanotube. Unparalleled properties of graphene such as electron mobility and high thermal conductivity, fracture resistance, suitable cause low light absorption and band gaps that make it possible to make electronic components with high speed in flexible and transparent electronic circuits using this nanomaterial. Graphene nanotransistors as well In terms of structure, they can have different types of back and hybrid gates (upper and lower). Hybrid gates (Not; or; And; Nand) are made of nanochips by nanotransistors.
The effect of nanotransistors based on carbon and graphene nanotubes on the development of military and biological industries
In the military nanoelectronics industry, two approaches are basically very important:
_Increase capabilities
Reducing the volume and size of nano-electronic structures (nano-chips)
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 and graphene nanotransistors.
Conclusion :
A simple basic structure that acts as a source in two metal joints, a drain and a carbon nanotube, which acts as a transistor channel, which is separated by an oxide layer from a high-density silicon ion. In this nano-electronic component, the nano-silicon substrate acts as a gate, which in this structure is called the back gate .
