Nanometer scale devices have the potential of replacing the CMOS based device as because of low power operation. Nanotechnology is the new and challenging field or technology of 21st century. Researchers were trying to scale the MOSFET to nano-metric scale from 180nm to 13 nm, but beyond 10nm the MOSFET faced quantum effects and thus the characteristic of normal MOSFET was altered to large extend. So, to cope up with technology development, researcher introduces new technology in which electronics work beyond 10 nm. The first transistor developed was SET, which used single electron for operation.
