CdZnTe crystal - Opis:
- 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/cm2. According to this model the Thermogradient 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 microscope. The influence of LR on the photoluminescence spectrahas show that at a threshold intensity of LR I=4 MW/cm2 creation of nanometer size structure begins. A graded band gap structure with optical window was formed at the top of nano-hills.
