KEYWORDS : Non equilibrium Green's Function (NEGF), Extended Huckel Theory (EHT), GNR, Self-Assembled Mono layers (SAM), ATK 12.2.0, Virtual Nano Lab, By comparing the I-V curves obtained using different metallic electrodes, we perceived that platinum showed maximum conductance and silver showed transmission of current amidst strongest coupling and thus affirmed to be the most effective material for electrodes for nanometer scale molecular junctions, when compared with other The simulated results revealed that among different electrode, the metallic electrodes showed maximum conductance of the order of 10 -5nS. The investigation of electron transport through GNR was accomplished by linking it to different metallic electrodes (Pt, Au and Ag) under different bias voltages within Keldysh's non- equilibrium Green Function formulism (NEGF) using Extended Huckel (EHT) semi empirical approach.
