Role of Electrode in Tuning Quantum Transport Properties of Oxygen Ended Zigzag Boron Carbide Nanoribbon

Abstract

Herein we report radical swing in quantum transport action in two-dimensional zigzag Boron carbide nanoribbon (ZBC2N) due to change in electrodes from Au (111) to Graphene. In case of Gold Electrode this system shows metallic feature having enormously high device current (thousands of nA) whereas with Graphene electrodes system gets insulating having negligible current. Results obtained have been substantiated through transmission spectra analysis obtained at equilibrium (zero bias) and finite bias.
