Self-organizing nanometer size structures are observed
on the surface of CdZnTe crystal irradiated by strongly
absorbed Nd:YAG laser irradiation (LR) at intensity range
of 4-12 MW/cm . According to this model the Thermogra-
dient effect has the main role in the interaction process of
LR and semiconductors. The surface state of the CdZnTe
under the influence of Nd:YAG laser irradiation has been
studied. A state has been defined by atom force microsco-
pe. The influence of LR on the photoluminescence spectra
has show that at a threshold intensity of LR I=4MW/cm
creation of nanometer size structure begins. A graded band
gap structure with optical window was formed at the top of
nano-hills.
