Application of the Inhomogeneous Sample Model in Piezoelectric Photothermal Spectroscopy of Zn1-x BexTe and Cd1-xMnxTe Mixed Crystals

This paper presents the basic details of the inhomogeneous sample model. This is one of the models that can be used for describing piezoelectric photothermal (PPT) spectra observed for mixed crystals. The experimental PPT spectra of Zn1−xBexTe and Cd1−xMnxTe mixed crystals preseInted in this paper exhibited the character of the crystal structure that was iInterpreted with the model of the inhomogeneous sample. The analysis of the spectra, performed with this model, enabled determination of both the basic optical parameters of the two crystal regions observed in the investigated samples and the composition of the crystals.
