A single p-type crystal of the mineral, pyrite (FeS2) was characterized photoacoustically using the transmission detection configuration. Photoacoustic (PA) amplitude and phase spectra were measured using a specially ...

The thermal diffusivity and free carrier diffusion coefficient of 12CaO×7 Al2O3 (C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
