An investigation of the switching characteristics of the As-Te-Ge glass, 1972
Item — Call number MU Thesis Lev
Identifier: b2088517
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...

Crystallite formation in chalcogenide glass as a function of temperature, 1971
Item — Call number MU Thesis Bea
Identifier: b2088111
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...

Study of the conduction properties of an amorphous semiconducting material over a wide temperature range, 1972
Item — Call number MU Thesis Bos
Identifier: b2088561
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...

Thermoluminescent studies on a LiF (TLD-100) crystal , 1974
Item — Call number MU Thesis Law
Identifier: b2088647
Abstract
The polarization properties of the light emitted by the thermoluminescent phosphor TLD-100 (Harshaw Chemical Co.), in crystalline form, is investigated for three different thermal and radiation histories (virgin, sensitized, and desensitized). The results of the investigation show no significant evidence of any type of polarization phenomena present for any of the conditions observed. This fact suggests that the luminescent centers responsible for the TL photons are probably anisotropic...
