Popis: An approach for characterization of some narrow-gap semiconductors from the minimum of the bulk reflectivity spectra in the plasma reflectivity region is presented. Determination of the concentration, effective mass, relaxation time and optical mobility of free carriers of IV-VI laser materials is given. A simple empirical method for estimation of the bulk reflectivity minimum in the case of interference spectra is proposed.
