Ab-initio simulation of single carbon-cluster electron device

A non-symmetrical C100 Fullerene molecule enclosed by three electrodes (source, drain, gate) made of gold has been chosen as the test configuration for single electron device (SET). Quantum transport of single electrons, under direct control of external electrodes has been rigorously simulated by density functional theory (DFT). The importance and the potential of the above device include operation at low power, and uniquely high charge sensitivity due to Coulomb blockade, possibly observable up to the room temperature.
