Transition of Growth Mode in Homoepitaxy on Metal Surface

Abstract

The process of the multilayer growth of Pt on Pt (111) is studied by using a Monte Carlo model with realistic physical parameters. The effects of the substrate temperature, the ES barrier, and the deposition rate on the growth mode have been investigated. Gradual transitions of the surface roughness from oscillatory to non-oscillatory behavior and then back to oscillatory behavior are observed while increasing the substrate temperature from 270 K to 620 K. It is found that the growth mode depends strongly on ES barrier over the whole temperatures and the deposition rate of atoms effectively affects the growth mode. The simulation results are consistent with many experimental observations for homoexpitaxy on a Pt (111) substrate.

Successive lag synchronization on dynamical networks with communication delay

“…It is well known that synchronization plays an important role in various fields, such as laser systems, communication systems, and parallel image processing. [1][2][3][4][5][6] In the research of complex dynamical networks, a variety of synchronization patterns have been defined and studied, including complete synchronization, [7] partial synchronization, [8] cluster synchronization, [9,10] projective synchronization, [11] phase synchronization, [12] lag synchronization (LS), [13] generalized synchronization, [14] etc. Among these patterns, the LS between two coupled systems has been studied extensively.…”
