Amorphous arsenic chalcogenide films modified using rare-earth complexes

Thin As2Se3 and As2S3 films modified by rare-earth complexes with organic ligands were grown by thermal evaporation. The use of rare-earth complexes made it possible to obtain amorphous films containing up to 2 at % rare earths. It was shown using a number of characterization techniques that the complexes were incorporated into the amorphous films without destruction. The absorption spectra of the films indicate that the introduction of the complexes influences their optical characteristics, which is probably associated with changes in the degree of disordering in the amorphous films.
