Nano Electromechanical System (NEMS) based on CNT: A Review

The last few years have witnessed the discovery, development and, in some cases, large-scale production and manufacturing of novel materials that lie within the nanometer scale. Such novel nanomaterials consist of inorganic or organic matter and in most cases have never been studied. Carbon nanotubes (CNTs) are one of them. They are nanometers in diameter and several millimeters in length and have a very broad range of electronic, thermal, and structural properties. Carbon nanotubes (CNTs) are ideal candidates for NEMS due to their chemical and physical structures, low masses and exceptional stiffness. Study of NEMS devices in the light of quantum mechanics requires understanding the interplay between the physical, geometrical and electrical parameters of the system.
