| Popis: | The processes at short-wave limit of the quenching of the photocurrent were studied. The possibility of creating a new type of device - a sensitive photometer (not on the intensity of light, but on its wavelength), and the combined temperature–voltage tester.The process of hole oscillation under photoexcitation from R-centers is investigated. The quantum yield for infrared light is determined. The effect of the applied voltage on the form of the spectral distribution curves of the photocurrent quenching was found and explained. The concentration of R-centers in the samples is calculated.This publication is a continuation of the reviews [1– 2]. For the sake of preservation of generality of work continuous numbering of sections is chosen. Numbers of formulas and figures are presented by sections. References in each article are given individually.Cadmium sulfide crystals are used in our studies as a convenient model material. Obtained results and constructed models are also applied to other semiconductors. |
