  • Abstract
    Photoacoustic (PA) technique in the gas microphone configuration has been employed to determine the thermal properties of GaAs samples using the phase angle measurements in the saturation region. The doped samples are either n-type (6.9×1017-5.6×1018 ) or p-type (2.08×1017-2.1×1020). The values of the thermal diffusivity (α) are found to change with the dopant concentration and type
