Optical and Magnetic Spectroscopy at Interfaces of Strained Semiconductor Superlattices
Abstract
This document summarizes research activities in a rapidly developing area of compound semiconductor superlattices. The area concerns materials based on the II-VI and, to a lesser extent, on the IV-VI compound semiconductors. Advances in modern epitaxy have made it possible to generate versatile layered structures. The emphasis in the work described below was especially on ultrathin layer structures where individual constituent layers approach atomic dimensions (monolayer limit). The description below provides a summary of recent accomplishments under ongoing ONR support. The new opportunities which exist for the proposed research are very much based on the physical understanding in terms of specific microscopic phenomena which has been accumulated in the principal investigators laboratory in the past two years, in concert with collaborators elsewhere. Of general physical interest were electronic, magnetic, and vibrational excitations near the 2D limit, especially in circumstances where coupling of such elementary excitations was a factor. The research also has a applied connection to optical and magneto-optical devices such as modulators and magneto-optical switches and storage elements.
