Sharvin resistance
Webb27 sep. 2006 · Transport through zinc blende magnetic semiconductors with magnetic domain walls is studied theoretically. We show that these magnetic domain walls have an intrinsic resistance due to the effective hole spin-orbit interaction. The intrinsic resistance is independent of the domain-wall shape and width and survives the adiabatic limit. For … Webb15 feb. 1993 · Sharvin resistance is observed in the constricted channel, whose length is extended to 20 μm as the effective width is decreased to 1.5 μm. This is related to the …

Webb7 sep. 2024 · At elevated temperatures, electron hydrodynamics efficiently eliminate the ‘bulk Landauer–Sharvin’ resistance, demonstrating that hydrodynamics can dramatically modify the well-established rules... WebbThe resistance is described by the Wexler’s formula, where both the Sharvin and Maxwell resistance contribute to the overall resistance of the contact. This kind of contact known as intermediate point-contact.
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.

In addition to the constriction effect described by this equation, the grain boundaries represent tunnel barriers, which can be quantified by reflection coefficients. We evaluated reflection coeffi-cients from the ratio of Sharvin resistance to the experimen-tal resistance ...
WebbSharvin Resistance = 4ρL/3πa2 (3) DISCUSSION On silicon, SSRM requires a sufficient load (10-12 Gpa) to produce a pressure induced phase transformation to the metallic β-tin phase of silicon. The high pressures involved require the use of a conductive solid diamond or a diamond coated probe.
