Photoconductivity of the Sulfide, Selenide, and Telluride of Zinc or Cadmium

摘要: The highlights of recent photoconductivity research on evaporated, powder, and sintered layers, single crystals photoconductors in the group ZnS, CdS, ZnSe, CdSe, ZnTe, CdTe are reviewed. following aspects discussed: spectral response, impurity sensitization, electrode contact problems, conductivity, mobility, speed photocurrent vs light intensity, temperature, infrared quenching, thermally stimulated current trapping, space-charge limited current, luminescence, photovoltaic effect, photoemissive surface photoconductivity. utility concepts Fermi-level demarcationlevel description many phenomena is briefly discussed.
