The report contains some new measurements on the thermal stability of As2Se3-As2Te3 glasses in which multiple crystallization processes have been found by differential scanning calorimetry. Discussion is given of the structure of As2Se3 films by comparing intensity and rdf curves obtained experimentally with theoretical curves derived from a microcrystallite model. The data strongly indicates that a glassy network model is more in accord with the experimental rdf than a microcrystalline model. Continuation of the work on the interaction between As2Se3 and Cu support grids is indicative of the formation of Cu2-xSe upon heat treatment. Finally a review article on electron diffraction rdfs of amorphous films prepared for the Physics of Thin Films is included.
