Investigation of the workfunction of metallic and/or metal/semi-conductor superlattices in order to optimize junctions with semi-conductors

Project: PHD

Project Details

Description

The metal workfunction is one of the important parameters determining the electronic properties of a metal/semiconductor contact. We investigate the metal worfunction of metal surfaces on top of metallic and metal/semiconductor superlattices. The influence on the workfunction of the thickness different layers is investigated theoritically and experimentally. We also vary the nature of the layer on top of the superlattice.
