摘要
Self-organizing structures of nanometer size are observed oil the surface of CdZnTe crystal irradiated by strongly absorbed Nd:YAG laser radiation (LR) at intensities within 4-12 MW/cm(2). The effect of exciton quantum confinement manifested by a shift to higher energies of the A(0),X exciton band of the photo-luminescent spectrum is present in structures of 10-15 nm in diameter at the top of nano-hills. A graded band gap structure with optical window is formed at the top of nano-hills. (C) 2009 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
