Abstract
In this paper, the analysis of the piezoelectric photothermal (PPT) spectra of a series of Cd1-xMnxTe mixed crystals is presented. The results indicated that the investigated mixed crystals exhibited nonuniform composition which is the result of diversified spatial distribution of manganese ions in the samples. Computations of the piezoelectric spectra, performed in multi-layer models of real samples, enabled determination of the percentage compositions of crystals in the two crystal regions approach. Different types of spatial distribution of manganese in the samples were revealed. Application of the models also enabled a quantitative estimation of the state of the surface of investigated samples.
