介绍了一种用于确定理想粘合能与界面间距的有效从头计算方法。可以从该粘合曲线中提取解理、表面和界面能量和强度。 Mo、Nb、V 和 ${\mathrm{MoSi}}_{2}$ 的结果准确地落在一条通用曲线上。该方法使得理想界面特性的从头计算变得容易处理,只需要在四个界面间距处进行计算。
An efficient ab initio method for determining ideal adhensive energy versus interfacial spacing is introduced. Cleavage, surface, and interfacial energies and strengths can be extracted from this adhesive curve. Results for Mo, Nb, V, and ${\mathrm{MoSi}}_{2}$ fall accurately on a single, universal curve. This method makes ab initio calculations for ideal interfacial properties tractable, requiring calculations at only four interfacial spacings.
