Abstract

Influence of Morphology and Structure on the Conductivity of Metallic Thin Films

Classical magnetoresistance is reduced and quantum effects due to the weak localization are enlarged when the scattering at grain bounderies in a crystalline film is increased. As Antimony shows both effects, it is suited to probe the influence of morphology and structure on the electronic properties of a thin film. We have grown Sb films on GaAs (110) at different evaporation rates with the same nominal thickness (30 layers) and correlated AFM and conductivity measurements.
