In this work, the results of the photoacoustic frequency characteristics research of a series of Cd1-ₓBeₓTe crystals, x = 0.01, 0.03, 0.1, after different surface treatments are presented. The samples showed thin surface layers resulting from a mechanical treatment, such as grinding and polishing their surfaces. The presented research aimed to investigate the possibility of determining the thickness of these surface layers resulting from their mechanical processing and to evaluate their thermal parameters with the frequency-domain photoacoustic (PA) method. It turned out that it is possible to simultaneously derive the thickness of the surface layer and its thermal parameters, such as thermal conductivity and thermal diffusivity, from fitting theoretical amplitude and phase PA characteristics to the experimental factors.
