摘要 基于密度函数理论(DFT)和Chen-Mbius晶格反演方法计算了Al-Al,Ni-Ni,Al-Ni原子间的相互作用势.根据获得的原子间相互作用势,通过采用最陡下降法和共轭梯度法实现对势能面全局最小点的搜索,获得n+m=13,19的Ni-Al团簇的稳态结构. Studied the universal interatomic potentials between Al-Al,Ni-Ni and Al-Ni using the Chen's lattice inversion method and density function theory (DFT). On the base of data calculated, using method of Conjugate Gradient the study concentrated on the stable geometry structure of Al-Ni clusters with 13 and 19 atoms.
