对可能的LiF簇结构进行全局搜索,直到(LiF)(8)。该方法是基于模拟退火,其中所有的能量进行评估的从头算水平。此外,阈值算法被用来确定这些结构之间的过渡的能量障碍,为集团(LiF)(4),再次在从头算水平上,并获得相应的树图。(C)2010年美国物理学会。[doi:10.1063/1.3455708]
A global search for possible LiF cluster structures is performed up to (LiF)(8). The method is based on simulated annealing, where all the energies are evaluated on the ab initio level. In addition, the threshold algorithm is employed to determine the energy barriers for the transitions among these structures, for the cluster (LiF)(4), again on the ab initio level, and the corresponding tree graph is obtained.
