Study of infrared quenching in silicide-silicon-silicide structures

Infrared quenching (IR Q) in silicide-silicon-silicide and silicide-silicon-metal structures has been studied. Silicides are obtained through the process of diffusion doping of silicon with manganese atoms. Infrared quenching was detected in the irradiation energy range of 0.31-0.75 eV when illuminated with local light hv≥Eg. Attachment levels for electrons were found: Ec-0.31 eV, Ec-0.38 eV, Ec-0.51 eV. The long-wave limit of photoconductivity (PC) was established to be 0.38 eV by studying the spectral characteristics of silicide-silicon-silicide structures.
