Abstract:
Twenty-five sample compositions were prepared from combinations of the elements Sb, As, Bi, Se, S, Te, and Tl. Twelve compositions were AMORPHOUS IN STRUCTURE, WHILE THE REMAINDER WERE DIPHASAL CONTAINING BOTH AMORPHOUS AND CRYSTALLINE PHASES. The amorphous materials all possessed an exponential resistivitytemperature relationship with negative temperature coefficient. The resistivity values for the diphasal materials with a high degree of crystallinity were practically independent of temperature, while a number of the slightly crystalline samples showed an apparent transition from crystalline to amorphous properties. All of the amorphous materials and most of the diphasal materials had a positive Seebeck coefficient. Room temperature Hall constant values were determined for a number of the new compositions and also for compositions in the series As2Te3-As2Se3. The thermal conductivity values for the materials tested increased as the degree of crystallinity was increased. Author
