- Title
Interaction Effects on AC Conductivity in Disordered Metallic Thin Films.
- Authors
Yang, Y. H.
- Abstract
The interaction theory has been generalized to the case of anisotropic disordered electron systems. The interaction correction to ac conductivity in a disordered metallic thin film has been calculated in the weakly localized regime. The result turns out that the frequency dependence of this correction changes from three-dimensional (3D) to twodimensional (2D) behavior with decreasing the film thickness d, and the dimensional crossover occurs at d ∼ &radicD[sub z]/Ω;, with D[sub z], and Ω being the perpendicular diffusion constant and the applied frequency, respectively.
