Abstract
Phonon pulses which were optically induced in thin evaporated films of amorphous As2S3 have been studied with a superconducting NbN bolometer. The observed ballistic and diffusive heat propagation provides a measure of the phonon mean free path (m.f.p.). The results are related to the microscopic structural order of the chalcogenide glass as evidenced from previous optical and structural studies.
