It was recognized that Ag doping was a significant factor in determining the electrical characteristics of CdS that produce negative differential conductivity NDC necessary for high field domains HFD in CdS. Doping with nitrates of Ag and Al was a method of obtaining CdS crystals exhibiting such phenomena, attributed to field quenching caused by field enhanced ionization. However, very little was known about the relationship between doping and the electrical characteristics that produce NDC. In order to gain some understanding of this relationship, the study of the effects of Ag doping on NDC was undertaken. It was the main purpose of this study to get a reliable procedure for doping with Ag and Al to obtain crystals for further studies of NDC and field quenching, and to what microscopic processes may be involved in the doping.
