Abstract

This paper presents the results of the studies of a thermal diffusivity of a series of mixed Zn~1–x~Be~x~Se crystals by means of the piezoelectric technique. For determination of a thermal diffusivity of samples the method based on the measurement of the phase of the piezoelectric signal, in the rear configuration, as a function of a frequency of modulation was chosen. This method enabled analysis of the influence of Be concentration and the process of annealing of crystals on the values of their thermal diffusivities. (© 2006 WILEY‐VCH Verlag GmbH & Co.

Minority recombination lifetimes of n-type CdMgSe mixed crystals were estimated by using infrared photothermal radiometry (PTR) amplitude and phase frequency spectra. The results obtained by the PTR method indicate that the lifetimes of optically generated carriers in CdSe and Cd x Mg 1-x Se crystal
