Abstract

High-conductivity semiconductor films with low reflectance in the IR-region can be used as absorbing coatings of pyroelectric radiation detectors. The plasma reflectivity of InSb-CdSe and InSb-CdS solid solutions were studied both experimentally and theoretically. A computer simulation was made of the dependences of spectrum shape nd plasma minimum depth on the relaxation time (tau) and sample structure inhomogeneity parameter (Delta) . The calculated reflection spectra with suitable selection of (tau) and (Delta) were found to agree well with the experimental ones. The results can be used for reflecting structure inhomogeneity diagnostics.
