Cadmium Sulfide Photoconductive Sintered Layers

The preparat ion and performance of sintered photoconductive cadmium sul-fide layers have been described. Although the photoconductive characteristics are direct ly dependent on composition, layer preparat ive techniques, and geom-etry of the unit, these parameters may be predicted and control led to give a resultant reproducible layer of desired electrical and optical characteristics. The use of photoconduct ive cadmium sulf ide in electronic devices, such as l ight ampl i f iers and image converters, has increased great ly dur ing the past few years (1-4). These devices usua l ly have neces-s i tated fabr icat ion of photoconduct ive layers of large surface area. Such layers can be achieved most read i ly by means of powdered layer (5), s intered layer (1,3) , d ie lectr ic imbedment, or evaporated f i lm (7) techniques. S intered layers have becom
