F原子与SiC(100)表面相互作用的分子动力学模拟
Molecular dynamics simulations of energy effects on atorn F interaction with SiC(100)
摘要
Abstract
In this study, molecular dynamics simulations are used to investigate atom F interacting with SiC at 300 K. Simulation results show that with the saturation of the deposition of F atoms on the surface, the compositions (SiFx and CFx groups (x4)) in the reaction layer reach a steady state. When incident energy is less than 6 eV, no etching is observed. With incident energy increasing, the etching yields of Si and C atoms increase. It is found that Si atoms are preferentially removed. For etching products, SiF4 is dominant. And the main etching mechanism of Si atoms is chemical etching.关键词
