Abstract
Modeling of quantum transport based on the non-equilibrium Green functions is presented in resonant tunneling diodes (RTD's) where realistic band structures, space charge effect, and scattering effects are taken into account. We have developed a multiband, non-equilibrium Green function and Poisson simulator that employs multi-band (MB) tight binding calculation using a sp 3s ∗ hybridization. As a result, we have found that the multiband nature and polar optical phonon scattering effects significantly change the results of conventional RTD simulations.
