In an article soon to be published in\u00a0Communications Physics<\/a><\/em>, a multi-institutional research team led by the University of Osaka announces the successful observation of the so-called superconducting diode effect in an Fe(Se,Te)\/FeTe heterostructure.<\/p>\n\n\n\n

The article describes a series of experiments in which the material developed a preference for current to flow in a particular direction, a phenomenon known as rectification, under a broad range of temperatures and magnetic fields.<\/p>\n\n\n\n

Essentially every electronic device in use today involves semiconductors, which can either inhibit or enhance the flow of electrons in one direction, allowing precise control over electrical signals. A longtime goal of physicists has been to merge this technology with superconductors, which have effectively no electrical resistance and can thus transport charges with perfect efficiency. However, to date, success has been limited.<\/p>\n\n\n\n

\u201cWhen it comes to superconductors, the choice of material is critical,\u201d explains Junichi Shiogai. \u201cIron selenide telluride has ideal properties such as a high transition temperature, critical magnetic field, and critical current density. This means that the range of parameters for which the effect can appear is large, giving us the best chance for success.\u201d<\/p>\n\n\n\n

Indeed, when a magnetic field was applied to their system, there was a significant shift in current directionality. The effect also increased as the magnetic field strength was increased and as the temperature was decreased. By analyzing the data while these parameters were varied, the team was able to devise a coherent explanation for the effect.<\/p>\n\n\n\n

\u201cUntil now, the mechanism of this effect has mostly been a mystery,\u201d says Shiogai. \u201cOur experiments reveal that the pinning of quantum vortices generated by the magnetic field plays a crucial role.\u201d<\/p>\n\n\n\n

The research team found that a strong spin-orbit interaction alters the asymmetric pinning potential so that vortices remain more stuck in one direction than the other, creating the breaking of symmetry needed to realize rectification. A strong linear correlation between the diode efficiency and the strength of polarization confirmed their hypothesis.<\/p>\n\n\n\n

\u201cWe are optimistic that these results can be applied to develop an ideal rectification device that paves the way for ultra-low energy electronics built from superconductors,\u201d says Shiogai. Thanks to the team\u2019s research, the future of such superconductors is indeed looking bright.<\/p>\n","protected":false},"excerpt":{"rendered":"
