Discovering, Enhancing and Engineering Two-Dimensional Superconductivity
Abstract
Advanced superconducting materials are important to a wide range of electronic applications of broad interests to air force and DoD applications, ranging from high frequency electronics, sensing techniques to future quantum technologies. High quality superconducting materials with highly controlled quantum electronic properties are essential to the development of next-generation superconducting devices achieving functionalities that are inaccessible with existing superconducting materials. Recent advances in two-dimensional (2D) quantum materials are rapidly expanding the class of high-quality, atomically thin crystalline superconductors, especially in the novel category where superconductivity emerges from non-superconducting mother materials. Such situations are currently rare; yet there are outstanding examples, such as the gate-tuned superconductivity in monolayer insulator tungsten ditelluride. The electronic property of such a material can be remarkably tuned between the two opposite extremes, i.e., a superconducting state and a strongly insulating state, by applying only a small voltage to the gate in a fashion of a field-effect transistor. Such novel 2D superconductors provide fascinating opportunities for both discovering new types of superconductivity and creating next-generation superconducting devices.
