Two-dimensional materials offer a unique opportunity to explore superconductivity in the two-dimensional (2D) limit with low disorder. IRG1 creates heterostructures of high-quality monolayers of superconductors encapsulated within insulating boron nitride, which provides protection from external disorder and oxidation.
The coupling of phonons to electrons, excitons and other phonons plays a defining role in material properties, including charge and energy transport, light emission, and superconductivity. In atomic solids such as Si or GaAs, phonons are delocalized over the three-dimensional (3D) lattice and are determined by bonding and crystal symmetry. In molecular materials, by contrast, localized molecular vibrations couple to electrons to produce, for example, high temperature superconductivity, as in A3C60.
An important goal in electronics is to reduce power use without sacrificing performance. In spintronics this can be accomplished by increasing the rate of charge to spin conversion. We show that one of the most efficient means of converting charge to spin information uses a topological insulator and voltages instead of currents.
