L12-Al3Li金属间化合物点缺陷浓度的第一原理计算
The structures, electronic properties, and surface energies of low-index surfaces of L12-Al3Sc intermetallic were studied systematically by the first-principles calculations based on density functional theory. The calculated results show that the relaxations are mainly localized within the outermost layer...
