DEVELOPMENT OF A FAST SOLID-STATE ULTRAVIOLET PHOTODETECTOR

Abstract

The objective of this work was to develop a fast solid-state ultraviolet detector. Efforts were concentrated on photovoltaic devices using metal semiconductor barrier layers. Peak detectivities of the order of 10 to the 9th cm (cps to the half power) watt and time constants of less than 120 microsec were achieved with both ZnS (lambda peak 339 millimicron) and TiO2 (lambda peak 320 millimicron). MgO was found to be photo conductive when exposed to radiation of wave length less than 260 millimicron. Trapping states in TiO2 were investigated by means of the method of space charge-limited currents.
