W: Molecular & Quantum Acoustics. - 2002, Vol. 23, s. 100-115Streszczenie: This paper is an introduction to the theory of multi-layer models developed for the purpose of qualitative and quantitative analysis of the piezoelectric photoacoustic spectra of real semiconductor samples. The theory comprises, among others, the new temperature distribution formula necessary for the computations of the piezoelectric characteristics, both frequency and spectral, and the transformation formula of the energy of photons to the optical adsorption coefficient being the function of several optical parameters. In the main part of the paper four multi-layers models of real samples are presented and the characteristic features of the spectra connected with these models are shown and discussed. The following multi-layer models are analyzed: an inactive layer model, a depletion layer model, a model of a heterogeneous sample and a model of enriched layer.
