Influence of grain boundaries and surface Debye temperature on the electrical resistance of thin gold films

The electrical resistivity of thin Au films deposited on amorphous substrates is found to increase with decreasing film thickness. The temp.-dependent part of the resistivity, however, is independent of the film thickness. This observation cannot be reconciled with existing theories that deal with s...

Zusammenfassung:	The electrical resistivity of thin Au films deposited on amorphous substrates is found to increase with decreasing film thickness. The temp.-dependent part of the resistivity, however, is independent of the film thickness. This observation cannot be reconciled with existing theories that deal with surface scattering effects. Electron scattering at grain boundaries is shown to explain the measurements. Moreover, the main effect of the surface appears to be a change in the effective Debye temp. 14 ref.--AA
