PERSPECTIVES OF NANOTECHNOLOGY FOR RF
AND TERAHERTZ ELECTRONICS
[attachment=66002]
INTRODUCTION
Matter or structures at dimensions below 100 nm down to atomic
dimensions of the order of 1 nm is called nano or nanoscale matter.
Advances in nanotechnology have led to the development of nano RF
or terahertz devices.
NANOTECHNOLOGY WITH NANOCARBON
CNTs are used as electron emitters for field emission sources.
High current output based on field emission in the nanocarbon
structure in a vacuum environment.
CNTs are also applicable in nonvacuum devices by mixing them with
CL phosphors
CNT-FET
A carbon nanotube field-effect transistor (CNTFET) .
It refers to a field-effect transistor that utilizes a single carbon
nanotube or an array of carbon nanotubes as the channel material
instead of bulk silicon in the traditional MOSFET structure.
First demonstrated in 1998, there have been major developments in
CNTFETs.
CONCLUSION
Significant changes like :
In displays.
In lighting.
In nanoelectronics.
Potential improvement using nanocarbons.
