摘要: In this work the possibility of simultaneous determination thermal and transport properties thin films using a photoacoustic method was investigated. The amorphous GeSe films, which were evaporated on quartz substrata, examined by measuring their amplitude phase spectra as function modulated optical laser beam frequency. measurements performed in specially constructed cell enabled excitation sample one side detection acoustic response other. Thermal diffusivity (diffusivity coefficient, recombination time, surface velocity) determined comparing experimental results calculated theoretical spectra.
