Webb15 mars 1994 · The resistance of a wire is calculated from the ballistic up to the diffusive transport regime through a semiclassical transmission approach. A formula is derived which describes the transition from the Shravin resistance to the Drude resistance when the mean free path becomes comparable to the wire length. Webb1 jan. 2014 · 4.2.1 Resistance of a Sharvin Contact. Sharvin considered the transport of electrons through a small aperture connecting two electrodes in the case where the size \(d\) of this aperture is smaller than the electrons mean free path \(l\) (Fig. 4.1).He remarked that in spite of the absence of scattering this contact has a finite resistance.
WebbThe intrinsic resistance is independent of the domain wall shape and width, and survives the adiabatic limit. For typical parameters, the intrinsic domain wall resistance is comparable to the Sharvin resistance and should be experimentally measurable.
