Abstract : DESCRIPTORS: (Theory and, Experimental data on, *Thermoelectricity, Electric power production, Cooling, Semiconductors, Diodes, Materials, Alloys, Lead alloys, Tellurides.) (Inter metallic compounds, Bismuth alloys, Antimony alloys, Tellurium alloys, Selenium alloys.) (Physical properties, Crystal structure, Elec trical conductance, Thermal conductivity, agnetohydrodynamics.) Tables. Open-ended T ERMS: Energ conversion. Materials research has continued in the examination of the II-VI, IV-VI and V-VI compound systems and several types of semiconductor devices have been investigated. A NEW METHOD OF DETERMINING THE CARRIER EFFECTIVE MASS FROM INFRARED REFLECTIONS HAS BEEN DEVELOPED IN CONNECTION WITH THE INVESTIGATION F THE ANOMALO S THERMAL CONDECTRIC PARAMETER OF THE Bi-Se-Te-Sb system are reported throughout the composition range. The electrical characteristics of indium-doped p-n junctions in CdTe are described. The use of p-n junctions as photovoltaic converters with high photon densities produced by a thermal source is examined. A study of the germanium oscillistor is presented and the preliminary experimental results are discusctivity and electronic propertie of PbTe. the temperature dependances of the thermoelectric parameter of the Bi-Se-Te-Sb system are reported throughout the composition range. The electrical characteristics of indium-doped p-n junctions in CdTe are described. The use of p-n junctions as photovoltaic converters with high photon densities produced by a thermal source is examined. A study of the germanium oscillistor is presented and the preliminary experimental results are discussed. An Esaki diode DC-AC converter is under investigation and design criteria for this device are described. (Author)
