NANOELECTRONICS IN RADIO FREQUENCY TECHNOLOGY Objective of presentation This aims for further miniaturization of circuit element below 100nm down to physical limit of CMOS technology and complete system interaction on chip. 123456 WHAT IS NANOTECHNOLOGY? It
characterizes the understanding and control
of matter at dimensions under 100 nm
are called nanoscale dimensions. nano Silicon Nanoelectronics This branch works in combining various types of chips in miniaturized system in package. Graphene Strictly 2-D material.
Monoatomic layer of Carbon atom. Thinnest & Strongest known material. Due to interesting properties of Graphene ...
It's widely used for RF applications and
also gives much better output as dual-gate graphene
field-effect transistor than the regular Si MOSFET's. Carbon Nanotubes CNTs are cylindrical structures of carbon(C) atoms arranged in a honeycomb pattern. It can be considered as a graphene layer rolled up to form a seamless cynlinder. The possibility to adjust the electric transport properties without the need
of doping as req. in conventional semiconductors makes CNTs so attractive
for future electronics. Moreover, CNTs exhibit an extermely high modulus of elasticity and high thermal conductance. This is the major reason why CNTs are so widely used in numerous applications some of these are :- CNT Capacitors for energy storage CNTs are used to make Supercapacitors
these are built from different kinds of
multiwalled CNT electrodes.
This yields energy storage capacity
much higher than best batteries. CNT Transistors for Radio Frequency Applications CNTs are base materials for flexible ICs, esp. for
consumer applications. Other
applications Spin flip electronics devices Single-Electron devices
Memristor Devices Light transport in Nanowires Superconducting Quantum interference devices Quantum Cellular Automata (QCA) CONCLUSION In this presentation i have attempted to give an overview of the impact of nanoelectronics on RF technology.
Today the development of nanoelectronics is highly market driven since the push for progress requires tremendous investments. The continuous technological progress in CMOS technology, following Moore’s law and the extensions more and more than certainly offers large room for progress, however, saturation already appears on the horizon.
Long-term research and development in direction of novel materials, novel technologies, and novel device concepts is of great importance to maintain the competitiveness of electronics industry.
The next 20 years of development of nanoelectronics will be extremely challenging By: ASHWARYA JOSHI
