晶体表面的自组织被研究为存在表面应力时的二维旋节线分解。考虑晶体各向异性，计算 (001) 立方晶体表面的弹性格林函数。数值计算表明，相分离是由域边界能量和长程弹性相互作用之间的相互作用驱动的。在相分离过程的后期，根据表面覆盖度和晶体弹性常数，出现具有不同纳米图案的稳态。
Self-organization on crystal surface is studied as a two dimensional spinodal decomposition in presence of a surface stress. The elastic Green function is calculated for a (001) cubic crystal surface taking into account the crystal anisotropy. Numerical calculations show that the phase separation is driven by the interplay between domain boundary energy and long range elastic interactions. At late stage of the phase separation process, a steady state appears with different nanometric patterns according to the surface coverage and the crystal elastic constants.
