Thermal diffusivity of sintered 12CaO x 7Al(2)O(3)
(Springer Heidelberg, Heidelberg, 2008)
The thermal diffusivity and free carrier diffusion coefficient of 12CaO x 7 Al2O3 ( C12A7) sintered for different times in air or hydrogen followed by treatment with UV light were determined from photoacoustic phase and ...
Photoacoustic characterization of natural mineral pyrite (FeS2)
(Springer Heidelberg, Heidelberg, 2008)
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 ...
Photoacoustic and optical properties of zinc-stannate thin films
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Thin films of single-phase zinc-stannate (Zn2SnO4) were grown by rf magnetron sputtering onto glass substrates. Transmission in the visible range was measured allowing determination of the energy gap and thickness of ...
Photoacoustic determination of thermal and electron transport properties of single crystal NiO
(E D P Sciences, Les Ulis Cedex A, 2005)
Thermal and electron transport properties of single crystal NiO were determined using the photoacoustic technique. NiO single crystals were prepared using the Verneuil method and were easily cleaved parallel to the (100) ...
