标题： Perpendicular-current Studies of Electron Transport Across Metal/Metal Interfaces

摘要： 我们回顾了目前在垂直于平面（CPP）几何中，电子在两种不同金属（M1/M2）界面散射方面的所学内容。 在这种几何结构中，固有量是比电阻，AR，即CPP电流通过的面积与CPP电阻的乘积。 我们描述了非磁性/非磁性（N1/N2）和铁磁性/非磁性（F/N）对的结果。 我们特别关注M1/M2晶格匹配的情况（即具有相同的晶体结构且晶格参数相差约1%），因为在这些情况下，无需自由参数的2AR计算结果与测量值惊人地吻合。 但我们也列出了并简要讨论了M1/M2不晶格匹配的情况，无论是晶体结构不同，还是晶格参数相差几个百分点。 在这些后一种情况下的2AR的已发表计算结果与测量值的吻合度较差。 显示英文摘要

摘要： We review what we have learned about the scattering of electrons by the interfaces between two different metals (M1/M2) in the current-perpendicular-to-plane (CPP) geometry. In this geometry, the intrinsic quantity is the specific resistance, AR, the product of the area through which the CPP current flows times the CPP resistance. We describe results for both non-magnetic/non-magnetic (N1/N2) and ferromagnetic/non-magnetic (F/N) pairs. We focus especially upon cases where M1/M2 are lattice matched (i.e., have the same crystal structure and the same lattice parameters to within ~ 1%), because in these cases no-free-parameter calculations of 2AR agree surprisingly well with measured values. But we also list and briefly discuss cases where M1/M2 are not lattice matched, either having different crystal structures, or lattice parameters that differ by several percent. The published calculations of 2AR in these latter cases do not agree so well with measured values.
