Grain Boundary Scattering

The electrical conductivity of a polycrystalline metal film has been studied for a model in which the background scattering and grain boundary scattering are independent. The external surface electron scattering has been analyzed by assuming it to be independent of background scattering and thus the external surface scattering can be conveniently described with the Cottey method.

A theoretical model for the electrical conductivity size effect of square nanowires is proposed in this manuscript, which features combining the three main carrier scattering mechanisms in polycrystalline nanowires together, namely, background scattering, external surface scattering, as well as grain boundary scattering. Comparisons to traditional models and experiment data show that this model achieves a higher correlation with the experiment data.

Based on the theories so far developed, an approximate expression for the resistivity of metallic films is derived, which takes into account film thickness, grain diameter, as well as the coefficients of surface scattering and grain boundary scattering. The derived formulae are compared with the results achieved by other authors.
