Sharvin resistance
Webb20 aug. 2001 · The Sharvin resistance will thus be dominated by k F in the semiconductor, which is spin independent. Even in the ballistic regime, we thus obtain a spin independent resistance between the ferromagnetic contacts which is approximately 26 kΩ ( w −1 k F −1 ) for one spin channel.

WebbIt has long been realized that even a perfectly clean electronic system harbors a Landauer-Sharvin resistance, inversely proportional to the number of its conduction channels. 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.
The term contact resistance refers to the contribution to the total resistance of a system which can be attributed to the contacting interfaces of electrical leads and connections as opposed to the intrinsic resistance. This effect is described by the term electrical contact resistance (ECR) and arises as the result of … Visa mer Here we need to distinguish the contact resistance evaluation in two-electrode systems (e.g. diodes) and three-electrode systems (e.g. transistors). For two electrode systems the specific contact resistivity is … Visa mer For given physical and mechanical material properties, parameters that govern the magnitude of electrical contact resistance (ECR) and its variation at an interface relate primarily to surface structure and applied load (Contact mechanics). … Visa mer Measurements of thermal conductivity are also subject to contact resistance, with particular significance in heat transport through granular media. Similarly, a drop in hydrostatic pressure (analogous … Visa mer • Contact cleaner • Wetting current Visa mer When a conductor has spatial dimensions close to $${\displaystyle 2\pi /k_{\text{F}}}$$, where $${\displaystyle k_{\text{F}}}$$ is Fermi wavevector of the conducting material, Ohm's law does not hold anymore. These small devices are called Visa mer Bad contacts are the cause of failure or poor performance in a wide variety of electrical devices. For example, corroded jumper cable clamps can frustrate attempts to start a vehicle that has a low battery. Dirty or corroded contacts on a fuse or its holder can give … Visa mer • Pitney, Kenneth E.

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.
