Uni-modal, not bi-modal, of abnormal grain growth has been observed in (111) oriented and nano-twinned Cu films. Because of the highly anisotropic microstructure, our kinetic analysis and calculation showed that it is the mobility which dominates the uni-modal growth, in which the lateral growth rate can be two orders of magnitude higher than the vertical growth rate. As a consequence, the abnormal grain growth has been converted from bi-modal to uni-modal.

在（111）取向和纳米孪晶铜薄膜中观察到的异常晶粒生长是单峰的，而非双峰的。由于微观结构具有高度各向异性，我们的动力学分析和计算表明，是迁移率主导了单峰生长，其中横向生长速率可比纵向生长速率高两个数量级。因此，异常晶粒生长已从双峰转变为单峰。
