The Effect of Nanotransistors Based on Carbon Nanotubes and Graphene in The Development of Military and Biological industries

Note: The basic simple structure, which has two metal connections as the source and drain, and the carbon nanotube as the transistor channel, which is separated from the silicon substrate with a high gross density by an oxide layer. In this nano-electronic part, the nano-silicon substrate plays the role of the gate, which is called the back gate in this structure  .

Then the upper gate nano-transistor  , which was suitable for use in integrated circuits  , with the addition of an upper gate that  is separated from the nano-tube channel by a thin layer of oxide,  graphene nano-transistors  are similar to carbon nano-tube-based transistors. with the difference that instead of carbon nanotubes,  graphene is used in its channel.  Graphene's unique properties such as electron mobility and  high thermal conductivity, resistance to fracture,   suitable for  low light absorption and band gap  make it possible to make high-speed electronic components  in flexible and  transparent electronic circuits using this nanomaterial.  In terms of structure, graphene nanotransistors  can  have back and combined gates (upper and lower). Combined gates (Not; or; And; Nand) are used in the manufacture of nanochips by nanotransistors.

The effect of nanotransistors based on carbon nanotubes and graphene in the development of military and biological industries

There are basically 2 very important approaches in military nanoelectronics industries:

_Increasing capabilities

_Reducing the volume and size of nanoelectronic structures (nanochips).

The design , manufacture, development and use of products whose size is in the range of  1 nm to  100 nm  is called nanoelectronics. In fact, we are talking about miniaturization, which allows for more contact, more activity, and an increase in area. Nano is a new scale in technologies and a new approach in all disciplines, and it gives mankind the ability to expand its involvement in the structure of materials and design and manufacture in very small dimensions and in all technologies. that the human being has already achieved, to have an effect . And this trend has been noticed in the production of electronic and biological nanotechnology. Implantable nanochips in the body and military industries depend on progress in the field of carbon tube and graphene nanotransistors.

Conclusion:

The basic simple structure, which plays the role of source and drain in two metallic connections, and the carbon nanotube plays the role of the transistor channel, which is separated from the silicon substrate with a high gross density by an oxide layer. In this nano-electronic part, the nano-silicon substrate plays the role of the gate, which is called the back gate in this structure  .
