WebAug 26, 2014 · The ability to manipulate spin-polarized supercurrents could enable the development of superconducting spintronic devices whose performance exceeds that of conventional spintronics. Banerjee et al ... WebSep 28, 2006 · Several different materials have been used to weakly couple superconductors, such as tunnel barriers, normal metals, or semiconductors. Here, we study supercurrents through a quantum dot created in a semiconductor nanowire by local electrostatic gating.

WebMar 3, 2024 · The appearance of localized supercurrents at the edges of a Josephson junction is generally attributed to the topology of the electronic band structure and edge states. (1) Edge states and the accompanying edge currents are typically found in ultraclean systems such as 2D electron gases, (2) nanowires, (3) and graphene. WebThe maximum supercurrent is determined by a process called phase slip. Consider that a short piece of vortex line is nucleated at a surface on one side of the channel. This vortex expands, goes through the whole cross section of the … divyesh mangla chess

An argument in favour of the existence of such an effect was the fact that matrix elements ... ascribed the supercurrents seen to conduction through metallic shorts through the barrier layer. As supercurrents were not always seen, it seemed that the explanation in terms of shorts ... WebThe dc critical current depends directly on the quantum phase difference of the superconducting wave function on the two sides of the barrier.
