Electrolyte Electroreflectance and Automatic Scanning Ellipsometry Characterization of Mercury Cadmium Telluride. Revision
Abstract
The optical of bulk , epitaxial, and surface treated, e.g. oxidized, mercury cadmium telluride by electrolyte electroreflectance, automatic scanning ellipsometry, and reflectance were experimentally and theoretically unified to establish a basis for in situ nondestructive evaluation of composition, crystal quality, and surface and interface properties. Specifically, a generalized theory was developed and applied to yield a unified interpretation of experimental El transition energies and line widths and anomalies for the consistent determination of composition fraction, x- value, relative crystal quality, interface roughness, long range strain, and polarizability.
