QUANTUM ELECTRON DEVICES

Materials (III-V and II-VI alloys, silicon). Technologies of semiconductor growth. Electronic structure of inverse layers, quantum wells and superlattices. Quantum effects in heterostructure transistors. Resonant tunneling microstructures (tunneling probability and time, Esaki-Tsu formula, coherent resonant tunneling). Quantum interference devices (Aharonov-Bohm effect, quantum reflection transistors). Transport regimes of 1D and 0D electron gas (localization and resonant tunneling, universal conductance fluctuation). Single electron devices. Excitons. Light absorption by single electrons and excitons. Optical modulation. Quantum well, wire and dot lasers. Intersubband lasers. Quantum well infrared detectors.
