H. Naito et al., STRUCTURAL-CHANGES IN AMORPHOUS ARSENIC TRISELENIDE BELOW THE GLASS-TRANSITION TEMPERATURE, Journal of non-crystalline solids, 166, 1993, pp. 1239-1242
A structural change below the glass-transition temperature in a-As2Se3
has been probed with the time-of-flight and dielectric measurements.
A possible origin of this change is discussed.
