The Absorption by Free Carriers in n-type AgCuSe

Abstract

In the ternary compound of n-type AgCuSe the absorption by free carriers in the range 2.5-25 µ was observed. There are two processes of absorption on the spectrogram α∼(hν). The coefficient of optical absorption by free carriers of a charge, corresponds to the classical Droode-Lowrens theory. The spectral dependence of electronic losses -Jm ε -1(ω), dielectric constants ε 1 and ε 2 have been estimated
