论文摘要
在旋缺失分解,组成应力和扩散各向异性的存在下,考虑了退火,单晶表面合金膜中组成模式的演变。前者两种效应有助于整体相分离,但各向异性与表面晶体学方向相关,导致图案的平面内形成和方向。针对[110],[100]和[111]面向的FCC立方合金表面的各向异性参数对模式的影响。
Evolution of composition patterns in the annealed, single-crystal surface alloy film is considered in the presence of the spinodal decomposition, the compositional stress and the diffusion anisotropy. While the former two effects contribute to overall phase separation, the anisotropy, correlated with the surface crystallographic orientation, guides the in-plane formation and orientation of a pattern. The impacts of the anisotropy parameters on patterns are systematically computed for [110], [100], and [111]-oriented fcc cubic alloy surfaces.
