Photoacoustic characterization of the thermal properties of a semiconductor-glass two-layer system

Abstract

The photoacoustic technique is used to investigate the thermal properties of a two-layer system, of variable thickness, consisting of a semiconductor polycrystalline thin film and glass. It is shown that the thermal diffusivity and thermal conductivity are completely determined based upon the effective sample model proposed by Mansanares et al. [Phys. Rev. B 42, 4477 (1990)].
