Doping of silver bromide by ion implantation

The effects of implanting silver, phosphorus, and cadmium ions in silver bromide microcrystals were ascertained using the intrinsic photosensitivity of these devices. Defects caused by implantation controlled the photocarrier trapping. After removal of these defects by annealing, both cadmium and phosphorus were the controlling species and increased the internal photosensitivity of the microcrystals.
