Simulation study of tunneling devices with quantum confinement in source and drain

Abstract

The self-consistent DC analyses of the electron transport in coupled quantum well systems through two-dimensional (2D) computer simulation is presented. Tunneling in the device is driven by the local phase difference between ψs, and ψas, the symmetric and anti-symmetric wave functions in the coupled quantum well. The device simulation is performed using quantum device analysis by modal evaluation (QDAME) program that solves Schrodinger and Poisson equations. It is found that the coupled quantum well consists of Si/SiO2, which has been used for resonant tunneling device simulations.
