With the energy-density coherent potential approximation method, a series of calculations concerning the contribution from the morphology and dispersion of random media composed of core-shell spheres on the transport properties of random media are conducted in terms of the scattering-cross-section efficiency factor, mean free path, velocity of electromagnetic energy, and diffusion coefficient. It...
Cobalt-doped ZnO (Co:Zn is 1, 3 and 5 mol%) nanobelts were prepared by a multi-components precursor self-assembled method, and characterized by the scanning electronic microscopy (SEM), X-ray diffraction (XRD), surface photocurrent spectroscopy and surface photovoltage spectroscopy. The room-temperature gas sensing of oxygen and ethanol vapor was measured with irradiation of visible light. The sensitivity...
