We investigated the thermal and photothermal properties of an amorphous GaSe9 alloy produced by mechanical alloying considering the photoacoustic spectroscopy and differential scanning calorimetry (DSC) techniques. The room temperature thermal diffusivity of GaSe9 was determined using the open photoacoustic cell configuration considering the thermal diffusion and thermoelastic bending effects. The glass transition and crystallization processes were investigated through DSC measurements obtained at five heating rates, and glass transition, crystallization temperatures, and activation energies were determined. The crystallization mechanism was also determined. [ABSTRACT FROM AUTHOR] |
