For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane.

对于薄膜特别是柱状晶薄膜，当晶粒在膜平面内的尺寸大于膜厚时，柱状晶粒的上底面和下底面的面积将大于侧面的面积，因此薄膜中的晶粒生长除像整体材料中的晶粒生长一样考虑晶界能外，还需要考虑表面能和界面能，因为各向异性的表面能和界面能将导致薄膜中的异常晶粒生长和织构变化。

For thin polycrystalline films, especially those with columnar structure, once the diameter of grains on the film surface is larger than the film thickness, the total area of above and under basal planes (film-substrate interface) will be larger than that of side plane. Therefore besides the minimization of boundary energy in traditional bulk material, surface energy, interface energy would be considered due to the anisotropy of surface energy, interface energy being able to drive the grain growth and texture evolution in thin films.
