Multiband treatment of quantum transport in anisotropic semiconductors: Non-equilibrium Green's function

Abstract

Using the non-equilibrium Green's function and anti-bonding orbital model, a multiband treatment of quantum transport in an anisotropic semiconductor (Si-based) system is developed. In this study, we adopt Chiang's boundary treatment of the open boundary system into the non-equilibrium Green's function framework, and then an easy and powerful multiband treatment method is developed to solve the transmission coefficient of Si-based semiconductor quantum structures.
