随着器件尺寸的减小，界面开始主导电传输，因此必须能够可靠地描述它们如何传输和反射电子。对于一些几乎完美的晶格匹配的材料，我们从第一性原理计算的界面透明度的晶体取向的依赖性。非常值得注意的是，最大的各向异性预测的原型自由电子材料银和铝之间的界面，（111）和（001）界面之间的差异的质量因子为2。
As devices are reduced in size, interfaces start to dominate electrical transport, making it essential to be able to describe reliably how they transmit and reflect electrons. For a number of nearly perfectly lattice-matched materials, we calculate from first principles the dependence of the interface transparency on the crystal orientation. Quite remarkably, the largest anisotropy is predicted for interfaces between the prototype free-electron materials silver and aluminum, for which a massive factor of 2 difference between (111) and (001) interfaces is found.
