Abstract

This work presents an approach for the analysis of guided and quasi-guided modes in planar electron waveguides with arbitrarily shaped potential and arbitrary effective mass profiles. The Finite Element Method (FEM) allied to a Perfectly Matched Layer-Like (PML-Like) spatial mapping is used for the phase constant and the mode confinement computations. The adopted spatial transformation maps an infinitely large region, surrounding an open waveguide, to a layer of finite thickness.
