Resumo
We report theoretical analysis of charge transport process through a single glycine molecule utilizing graphene nanogaps. Density functional theory and non-equilibrium Green's function method are employed to investigate the transport properties of glycine inside the gap. The projected density of states, transmittance, and the current-voltage characteristics are determined with changes in the molecular orientation inside the nanogap of c.a 0.8 nm. The current values demonstrate a high sensitivity on the orientation of the molecule. The conductance of the molecule is also dependent on the voltage.
