| Abstract: | During interaction of pulsed laser radiation with the surface of polycrystalline cadmium sulfide films an enrichment of sulfur vacancies near the surface was previously observed. In this paper, the adsorption-desorption sensitivity (ADS) of the cadmium sulfide film to oxygen was determined by the temperature dependence of the dark current. In this case, the sulfur vacancies serve as adsorption centers. The presence of surface and volume components of ADS was detected. Here the surface portion of ADS remains essentially unchanged, but the volume component grows with increase in the radiation dose.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 82–85, March, 1990. |
