Popis:	t is established that the photocurrent spectrum I = f(λ) of a CdZnTe crystal depends on the configuration and frequency of an external electric field applied to the sample. In particular, the application of periodic field pulses in the Haar wavelet form leads to modification of the spectrum at frequencies corresponding to certain maxima of the wavelet coefficients. It is demonstrated that, by representing the photore-sponse spectrum in the form of parametric signatures plotted as I(λ) versus dI/dλ, it is possible to separate and evaluate the partial contributions of various photosensitive centers in the given crystal.
