Structural Effects on Electrical Properties in Amorphous Semiconducting Materials

Abstract

During this report period, work has been concentrated on a survey of the structure, electrical and magnetic properties of transition metal oxide- phosphate glasses and glasses in the As2Te3-As2Se3 system which possess electrical or magnetic device potential. Results of magnetic and electrical observations in an FeO-P2O5 glass have revealed a surprisingly high degree of magnetic and structural order. Examination of a V2O5 - P2O5 glass has revealed a 'Phase transition' in the glass at a low temperature. Initial results on a CuO- P2O5 glass indicate that an extremely conductive film has been observed and bulk conduction of the same magnitude will be potentially useful in device applications. Work in the As2Te3-As2Se3 system has shown switching behavior which can be controlled with compositional variation. This material has also been used as a circuit element for a microwave oscillator which has operated in a transient mode at 5 GHz.
