摘要: 采用赝势方法计算TiN/VN超晶格薄膜的能带结构,并计算了TiN/VN超晶格原胞的总能量,进而得到了该材料的切变弹性模量C44随超晶格周期的变化关系,C44出现最大值时所对应的周期与实验值基本一致.

关键词: 超晶格, 赝势, 切变弹性模量C44

Abstract: The energy band structure of TiN/VN superlattice thin film is calculated using the pseudopotential method.The total energy of the TiN/VN superlattice cell is also calculated.Then the relationship between C44 and the period of superlattice λ is obtained.The superlattic period where C44 reaches the maximum basically accords with the experimental data.

Key words: superlattice, pseudopotential, shear elastic module C44
