The thermal behavior of thin selenium–tellurium (Se–Te) films was studied under non-isothermal conditions using differential scanning calorimetry. The glass transition kinetics of the as-prepared thin films was found to change with increasing Te content; namely the activation energy of structural relaxation processes decreased from 355 to 245 kJ mol-1 of studiet films. In the glass-forming region the GFA criterion and relaxation data obtained for the thin films correlated very well with the results for bulk glasses. In the glass-forming region, the crystallization kinetics of thin films corresponded to that determined for very fine Se–Te powders.
