In this work characteristics of dissolution processes in chalcogenide
glassy semiconductors (illuminated and non-illuminated) were studied.
The main purpose of this work was studying different compounds of the
chalcogenide glassy semiconductors of the As-Se and As-S Systems and t
heir reciprocation with some selective solvents. The author of this do
cument and his instructor consider as the most significant result of t
his work the discovery of an effective positive solvent (gamma approxi
mate to 100) in As45S55 films.
