Electronic energy state and transmission properties study of parabolic double quantum well using Non-equilibrium Green function method

Abstract

We apply the non-equilibrium Green's function method based on the finite difference method to the parabolic double quantum well structure. In particular, we examine the effect of system parameters on transmission coefficient. The properties of the electronic state also studied as a function of the system parameters, such as, the well widths and depth. We also tested energy electronic state with calculating density of states.
