Abstract
Abstract The influence of the deposition time and the ratio of hydroxide to lead ion concentration in the precipitation solution on the photoconductive properties of chemically deposited PbS layers was investigated.From measurements of time constant, noise and resistance, it could be shown how the deposition conditions control the number of trapping centres and carrier density. The trapping centres may be connected with excess lead atoms deposited in the PbS lattice under the conditions of preparation
