The reason why the existence of cr underlayers enhanced the pma energy of tbco films is that the existence of cr underlayers leads to forming the columnar structure and enhancing the inner stress in tbco films , thereby , enhancing the pma energy
金属cr底层增强tbco薄膜垂直磁各向异性的主要原因是：金属cr底层的存在将可以使得tbco非晶垂直磁化膜内产生柱状结构，而且会增强薄膜的内应力，从而使得其磁各向异性能增加。
High quality znsxse1 - x thin film grown at the optimized temperature had the smoothest surface with lowest rms value of 1 . 2 nm and tem cross - sectional micrograph showing a well defined columnar structure . the dependence of substrate temperature , deposition rate and alloy composition to the structure of the film was discussed in the thesis . the developed theory named " quasi - structure area mode " can successfully explain the film growth mechanism of polycrystalline znsxse1 - x thin films deposited on ito substrate by mbe
研究了采用mbe系统沉积zns _ xse _ ( 1 - x )多晶薄膜的生长机理，分析了衬底温度、沉积速率及薄膜组分对薄膜微结构的影响，提出的“类结构区域模型”可以较完整地解释ito衬底上zns _ xse _ ( 1 - x )多晶薄膜生长的机理。
