Abstract

An organic molecule-based single-electron transistor (SET) is analysed by ab initio method using Density Functional Theory (DFT). Initially, benzene molecule is taken; two carbon atoms from benzene are replaced by boron atoms, and the structure of the molecule is optimized. The optimized structure C4H6B2 is kept above the gate dielectric in the island for weak coupling. The charge energies of device are calculated in both isolated and SET environment. We have done analysis by using different electrodes with gold (work function = 5.28 eV), osmium (work function = 5.93 eV) and caesium (work function = 2.14 eV) in SET environment. By charge stability diagrams, the conductance dependence of SET on gate voltage and bias potential are verified.
