用第一性原理分子动力学计算了mg7li合金的晶格常数。分子动力学使我们能够优化晶体结构。目前的计算是基于从头算伪势和超级单体方法。制备了mg7li - 1合金的两个超级电池,讨论了其结构的稳定性。我们还计算了mg7li1合金的体积模量。
We have used first principle molecular dynamics to calculate lattice constants of the Mg 7 Li 1 alloy. The molecular dynamics enables us to optimize the crystal structure. The present calculations are based on the ab initio pseudopotential and the supercell approach. Two supercells of the Mg 7 Li 1 alloy are made up to discuss the stability of structure. We have also calculated bulk modulus of the Mg 7 Li 1 alloy.
