Bordovskii, R. Castro] Tin impurity atoms occupy substitutional positions of lead and germanium in the structural network of Ge28.5Pb15S56.5 and Ge27Pb17Se56 glasses and are electrically inactive centers. Iron impurity atoms form donor levels in the mobility gap of the glasses and bring about a shift of the Fermi level from the midpoint of the mobility gap. This shift depends on the iron content.
