Abstract

The structure and optical characteristics (transmission spectra and dispersion of the refraction index) of nominally pure and mercury-modified amorphous Se100-xAsx films (x = 0, 3, 5, 7, 9) were studied. It was ascertained that nominally pure films are X-ray amorphous. Exposure of the films in mercury vapor leads to the formation of HgSe crystalline inclusions in their near-surface layers. The width of the pseudo-forbidden gap Eg and the refraction indices n2, n2' and n3 of both nominally pure (n2) and those exposed to mercury vapor (n2' and n3) films were determined. Significant changes in the n2' and n3 values of amorphous films are caused by structural transformations that occur in them during modification.
