Submillimeter Wave Spectroscopy of Heterojunction Superlattices: A Final Technical Report

Abstract

The general objectives of this research are to systematically investigate the interaction of electromagnetic radiation in the far infrared range with the charge carriers in semiconductor heterojunction superlattice structures. Experiments are performed on both the lattice-matched GaAs/Al sub XGa sub 1-xAs/GaAs heterojunction material structures and the strained-layer material of In sub xGa sub 1-xAs/GaAs heterostructure. In the former case, new electronic processes are discovered and their possible detector application is explored. In the latter case, the energy level structure is determined and the carrier dynamics are studied using the submillimeter wave spectroscopy.
