  1. Fourier analysis of scratches generated on m-GaN substrates during polishing

    Propagation of scratches on surface of m-plane GaN substrates due to polishing was studied by atomic force microscopy (AFM). The Fourier analysis of AFM images show that scratches propagate easier along {c-plane} and {a-plane} directions on m-plane GaN surface. This observation is an evidence of anisotropy of mechanical properties of GaN crystals in the micro-scale. This anisotropy is directly correlated with the symmetry and atomic arrangement of m-plane GaN.

  2. Synthesis of Cu vanadate nanorods for visible-light photocatalytic degradation of gentian violet

    Cu vanadate nanorods with monoclinic Cu5V2O10 phase and diameter of 50–300 nm were synthesized via the hydrothermal process using polymer polyvinyl pyrrolidone (PVP) as the surfactant. Gentian violet (GV) was used to evaluate the photocatalytic activites of the Cu vanadate nanorods. The Cu vanadate nanorods showed good photocatalytic activities for the GV degradation under solar light.

  3. Numerical investigation of carbon and silicon carbide contamination during the melting process of the Czochralski silicon crystal growth

    Xin Liu, Bing Gao, Satoshi Nakano and Koichi Kakimoto

    Article first published online: 17 FEB 2015 | DOI: 10.1002/crat.201500014

    Transient global modeling of heat and mass transport was performed for the melting process of the Czochralski silicon crystal growth. Carbon contaminations were predicted by the coupled model including six chemical reactions. Carbon contamination is remarkable in the melting and stabilization stages. Control of carbon contamination prior to growth is critical to the growth of high purity crystal.

  4. Cuprous oxide microcrystals via hydrothermal approach: morphology evolution and photocatalytic properties

    Chunxia Chai, Peng Peng, Xinjun Wang and Ke Li

    Article first published online: 12 FEB 2015 | DOI: 10.1002/crat.201400455

    Three morphological Cu2O microcrystals with differently exposed planes were prepared. The exposed planes were clearly characterized by XRD and SEM, and the radial six hollow branches microcrystals with exposed {110} planes present a higher degradation efficiency to methyl orange (MO).

  5. Synthesis of nanoflakes-based self-assembling crossed structure of stannous oxide and photocatalysis property

    The crossed architectures self-assembled by a significant amount of SnO nanoflakes have successfully been synthesized. The high photocatalytic activity in degradation of methyl orange has been obtained for the first time and the photodegradation proccess of methyl orange has been discussed. A possible growth mechanism for the self-assembling nanoflakes-based crossed SnO architecture has been proposed.
