摘要
A linear response method for computing the voltage drop in the high conductance regime is presented. It is applied to the study of both coherent and incoherent transport in model 1D, 2D, and 3D materials, within the non-equilibrium Green's function formalism. The method is shown to accurately reproduce self-consistent voltage drop results computed from first-principles, including the transition from low dimensional screening oscillations to higher dimensional near classical screening. Overall, the method provides an additional analysis technique in the "quantum transport toolbox" that is complementary to self-consistent methods (in the high conductance regime).
