Paper Abstract

Epitaxial growth techniques allow the precise growth of ultra thin semiconductor heterojunctions. The wave particle duality of electrons in such materials can be fully exploited in designing tailor made optical and electronic properties. The basic theory of electronic and optical properties of quantum wells described for the lattice matched GaAs/AlGaAs system. Optical modulation using the quantum confined Stark effect in p-i-n diodes and n-i-n phototransistors is described. Calculations showing the unique valence band warping effects in strained layer CdTe/CdZnTe quantum wells is presented. A CdTe/CdZnTe n-i-n optoelectronic device is described and performance discussed.
