Development of Qualitative Theories of the Fundamental Electronic Structure of Pure and, Impure Semiconductors.

摘要

The past five years of this project have been devoted to (development of qualitative theories of the fundamental electronic structure of pure and, impure semiconductors.) The basic theoretical tools and also conclusions relating to chiefly photoemission type experiments and to some extent spectroscopy of pure II-VI and III-V compounds are presented. Basic complete work relating to adsorbates and their spectra are reported. This investigation has the purpose of performing self-consistent energy band calculations on some of the II-VI compounds, such as cadmium sulfide, zinc oxide, and zinc sulfide. These materials have applications as phosphors (ZnS and CdS), as infrared detectors (ZnS), in photovoltaic cells (CdS-Cu2S or CdS-CdTe heterojunctions), in batteries (ZnO), as FETs (CdS), in heterojunction lasers (CdS), and even as acoustic amplifiers (CdS).
