Photo-conductivity in lead selenide Lee, Peter Arthur
Abstract
The method of preparation of photoconductive layers of lead selenide is described. Details are given of the construction, of cells using lead selenide as a detector for use in the infra-red region of the spectrum up to 7 microns. One such cell is shown to have a minimum detectable power of 10⁻¹⁰ watts within its sensitive spectral range. Experiments, are described on the conductivity and wavelength sensitivity as a function of the temperature of the layer. The effects of oxygen and heat treatments on such a layer are shown. These observations are used to draw conclusions concerning the mechanism of the photoconductivity in layers of lead selenide.
