Abstract This is a report on an experimental investigation into the switching characteristics of the As-Te-Ge glass undertaken in the Physics Department of Monmouth College. The report describes the preparation of the amorphous samples, discusses associated semiconductor theory, and presents a discussion on the results obtained. Graphs of log resistance vs 1/T for this glassy system are presented which clearly show an intrinsic conduction range down to about 40°C. Some evidence in the date of an...

Abstract Herein are presented the results of an experimental study of a ternary calcogenide glass of composition: 55 at.% As, 35 at.% Te, 10 at.% Ge. X-ray diffraction measurements of powder samples of the glass were made over a temperature range from room temperature (~23° C) to 440° C. These measurements show the glass to be in a non-cyrstalline amorphous state or short-range order state from room temperature up to a temperature of 220° C. From 220° to approximately 440° the material seems to...

Abstract Equipment was designed and built for measuring the resistance of an amorphous semiconducting bulk sample over the temperature range of -104 C to 300 C. The sample composition was 55% arsenic, 35% tellurium, and 10% germanium. The temperature range from -104 C to -41 C was found to exhibit extrinsic conductivity, while the range from -17 C to 100 C was explained on the basis of intrinsic conductivity. The intermediate temperature range of -41 C to -17 C was described as a range where both...
