Abstract:
In this paper, a brief review of CNT carbon nanotube transistors will be explained and then
the optimization methods will be discussed. Details of AC and DC transistor CNFET and
Characteristics of CNFET at high temperature also shows that unlike MOSFET flo below the
threshold for this type of component temperature is reduced, thus using CNFET at high
temperatures can be more quickly and less leakage current is achieved. Processes for the
synthesis of CNT are not complete, a subject of controversy in the field fluctuations of density
in CNT growth, as well as an analysis of the credit CNFET because sway density of CNT
could lead to complete failure CNFET, so to evaluate it, and we later CNFET applications in
comparison with CMOS logic circuits using the latest research, we'll CNFET.
Machine summary:
"Extensive research efforts to take advantage of carbon nanotube field-effect transistors (CNFETs) as an alternative or complement to future semiconductor components due to high Therapy, low defect structure and exceptional electrical characteristics, such as the transfer of quasi-ballistic (no scattering channels ballistic properties) makes them suitable for high speed and high performance circuits are designed.
It is expected that the ideal technology CNFET (in the sense that all carbon nanotubes are semiconductors similar thickness as well as quite a good position to Traznd) times faster than silicon CMOS, while the similar energy consumption [2].
In a carbon nanotube and graphene ribbons Chyralyty angular difference between the orientation of the resulting nanotube axis (Fig. 2) of CNT semiconductor field-effect transistors is the main reason for trying to make (CNFET).

AC and DC transistor characteristics CNTFET: Advances in semiconductor tube of carbon nanotube field- effect transistors with high performance has been remarkable.
8:conclusion According to numerous studies that CNFET face and optimization methods to solve the shortcomings of the challenge and despite the many advantages that these parts (CNFETs) compared to MOSFET are still a long way to industrial applications CNFET there, While still unwanted growth during manufacture of metal tubes CNT are also considered as a challenge and a negative impact on latency, power and performance are CNT-based circuits.
