Vn. Vasilkov et al., PHOTOELECTRIC PROPERTIES OF PB1-X-Y,SNXGEYTE, IN EPITAXIAL-FILMS AND ARRAY PHOTODETECTORS, Inorganic materials, 33(2), 1997, pp. 181-184
Photoelectric properties of Pb1-x-ySnxGeyTe:In epitaxial single-crysta
l films were measured in the temperature range 10-80 K at background r
adiation fluxes from 10(12) to 10(18) cm(-2) s(-1). The Lifetime of no
n equilibrium electrons was found to depend on composition, temperatur
e, and background flux. We propose a model for slow photocurrent relax
ation in the films studied and calculate threshold parameters of charg
e-accumulation array photodetectors.
