Outline of Final Research Achievements

To improve an analytical model of thermoreflectance method, the cross-plane thermal transport, generation, and propagation of coherent acoustic-phonon wave in thin Pt film-glass substrate have been comprehensively studied by applying the picosecond laser pump-probe method with different configurations. Significantly different time-dependent reflectance signals have been obtained in different configurations and an effect superposition model is proposed to account for cross plane thermal transport inducing ipsi- and contralateral temperature change in thin Pt film, propagation of coherent acoustic-phonon wave in thin Pt film and in glass substrate. The corresponding theoretical predictions match well with the experimental data. In addition, a metal oxide thin film was prepared by PLD method (Pulsed Laser Deposition), and its thermal conductivity was measured. Furthermore, the effects of high temperature atmosphere (600 degree celsius) on a molybdenum thin film were examined.
