Maliński, L. Bychto, A. Patryn, J. Gibkes, B.K. Bein, J. Pelzl.  aDane z autopsji.  aThis paper presents results of photoacoustic studies of porous silicon layers formed on silicon substrates with the method of constant current anodisation of c-Si in an aqueous solution of HF. The aim of the study was to determine the thermal diffusivity of the porous silicon layers and their optical absorption coefficients with the photoacoustic method using two wavelengths of the exciting light for the generation of thermal waves and measurement of thermal and optical parameters. 0aMateriały konferencyjne.1 aBYCHTO, Leszek.d1996 - .bPolitechnika Koszalińska - Wydział Elektroniki,cKatedra Elektroniki Ciała Stałego1 aPATRYN, Aleksy.d1996 - .bPolitechnika Koszalińska - Wydział Elektroniki,cKatedra Elektroniki Ciała Stałego22aWinter School on Wave and Quantum Acousticsn(34 ;d2000 ;cUstroń, Poland).0 iW :t34th Winter School on Wave and Quantum Acoustics, Ustroń, Poland, 28 February - 4 March 2005 / ed. by T.
