On the basis of the analysis of experimental results, a two-stage mechanism of nanocones formation on the irradiated surface of semiconductors by Nd:YAG laser is proposed for elementary semiconductors and solid solutions, such as Si, Ge, SiGe, and CdZnTe. Properties observed are explained in the frame of quantum confinement effect. The first stage of the(More)
Experimentally observed self-organization of a 2D lattice on the surface of Ge single crystal after irradiation by pulsed YAG:Nd laser is reported. The 2D lattice consists of nano-size elevations arranged in a pattern of C 6i point group symmetry and is characterized by translational symmetry with the period of 1μm. Calculations of time-dependent(More)
