Abstract

This project is guided to the preparation of a student to work in transport properties in a near future. It is intended to initiate and solidify analytical methods and knowledge for advanced numerical techniques. The candidate should calculated transmissivity and tunneling current in double-barrier systems. He will work with two models for the potential profile under applied voltage, one with 3D-2D-3D injection and another 2D-2D-3D injection which includes an analytical profile function to account for interface charge accumulation.
