Super - roughening as a disorder - dominated flat phase

– We study the phenomenon of super-roughening found on surfaces growing on disordered substrates. We consider a one-dimensional version of the problem for which the pure, ordered model exhibits a roughening phase transition. Extensive numerical simulations combined with analytical approximations indicate that super-roughening is a regime of asymp-totically flat surfaces with non-trivial, rough ...

Microstructure, optical properties, and catalytic performance of Cu2O-modified ZnO nanorods prepared by electrodeposition

Cu2O-modified ZnO nanorods are prepared by a two-step electrodeposition method on ITO substrates, and the deposition time of Cu2O is 0, 1, 5, and 10 min, respectively. Cu2O particles are embedded in the interspaces of the ZnO nanorods, and the amounts of the Cu2O particles increase obviously when the deposition time lasts longer. The peaks corresponding to ZnO nanorods and Cu2O particles are de...

Microstructure and optical properties of nanocrystalline Cu2O thin films prepared by electrodeposition

Cuprous oxide (Cu2O) thin films were prepared by using electrodeposition technique at different applied potentials (-0.1, -0.3, -0.5, -0.7, and -0.9 V) and were annealed in vacuum at a temperature of 100°C for 1 h. Microstructure and optical properties of these films have been investigated by X-ray diffractometer (XRD), field-emission scanning electron microscope (SEM), UV-visible (vis) spectro...

Chemical diffusion for CoO and Cu2O deduced from creep transitories

2014 The analysis of creep transitories after a change in oxygen partial pressure, allowed us to determine chemical diffusion coefficients for CoO and Cu2O, singleand polycrystals. The rate of equilibration of point defect concentrations is similar for all defects. Grain boundaries do not seem to accelerate the process. Tome 21 ? 6 JUIN 1986 Revue Phys. Appl. 21 (1986) 343-348 JUIN 1986,

Kinetic roughening in growth models with diffusion in higher dimensions

We present results of numerical simulations of kinetic roughening for a growth model with surface diffusion (the Wolf-Villain model) in 3+1 and 4+1 dimensions using lattices of a linear size up to L=64 in 3+1 D and L=32 in 4+1 D. The effective exponents calculated both from the surface width and from the height–height correlation function are much larger than those expected based on results in ...
