金属薄膜中的电导率计算

Conductivity Calculation in Metallic Film

考虑到杂质和表面粗糙的散射，运用量子统计的格林函数方法，计算金属薄膜中的电导率。计算表明：在薄膜系统中，来自杂质和表面粗糙散射的电导率都以π/KF（KF作为费米波矢值）为周期随厚度d振荡。

Taking into account impurities and rough surfaces scattering effects, using the Quantum-statistical Gree's function approach, We calculate the conductivity of metallic film. It is found that the conductivity from impurities and surfaces scattering show oscillations as afunction of its thickness with a Period of π/KF。
