Low dimensionality electronic devices based on heterodimensional Schottky contacts: Modeling and experimental results

This paper discusses the modeling and experimental results for a new family of electronic devices in which a Schottky metal is placed in direct contact to a low dimensionality structure such as a quantum-well or a quantum wire. Based on those principles, we experimentally demonstrate the improved performance of both a microwave varactor and a MSM photodetector. The results are explained in terms of a fully quantum mechanical model, by self-consistently solving Schrodinger and Poisson equations.
