We study a random-walk diffusion model for a restricted solid-on-solid (RSOS) condition, where a deposited particle is allowed to walk randomly until visiting a site satisfying the RSOS condition. The interface width W grows as tβ in early time, wit

A discrete growth model with quenched impurities driven by an external force is studied on a Sierpinski gasket substrate. At the critical force F c , the growth velocity v of the average interface height follows a power-law behavior v(t) ∼ t −δ

The effect of tensile strain on structural and ferroelectric properties of BiFeO3 epitaxial films was investigated. The films grown by pulsed laser deposition on MgAl2O4 (0 0 1) substrates revealed monoclinic structure deviated from the bulk rhombohe

Recent studies by a number of research groups have shown that the structure of epitaxial BiFeO3 (BFO) films changes drastically as a function of substrate-induced biaxial compression, with the crystal structure changing from one being nearly rhombohe

We introduce a restricted height model with conservation of the total number of particles. The surface width W (L, t) of our model follows a scaling formula W (L, t) = W 2 i − Lf(t/L) as a function of time t, where Wi and L are an intrinsic width a

In order to evaluate the degradation of the mechanical properties of Zr-based nuclear fuel cladding tubes under severe accident conditions such as a RIA (reactivity initiated accident) and LOCA (loss of coolant accident), mechanical tests that can pr

Recent advances in film synthesis have made it possible to investigate the properties of well-controlled interfaces in perovskite metal-oxides. A review of published experimental data and computational results indicate that so far most interfaces tha

A room-temperature electrochemical approach to synthesizing anisotropic platelike copper microcrystals and nanocrystals in the presence of potassium bromide is presented. Morphological and elemental characterization was performed using SEM, TEM, and

We have grown Ca${}_{2\ensuremath{-}x}$Sr${}_{x}$RuO${}_{4}$ ($x$ $=$ 0, 0.1, 0.5, and 2) epitaxial thin films using a pulsed laser deposition method and characterized their structures and magnetotransport properties. We find that the $x$ $=$ 0, 0.1,

Atomically flat SrTiO 3 (STO) substrates can be prepared by oxygen-annealing, however, step structures are known to be difficult to control. Various step structures of original substrates could be modified by growth of homoepitaxial films using laser
