TOPOLOGICAL SUPERCONDUCTING MATERIALS AND DEVICES
Abstract
The proposed project is a fundamental research program to search and develop new superconducting materials with topological properties with potential for future applications, building on known empirical and theoretical principles. Two main thrusts – involving materials synthesis and exploration, and assembly of device structures – will be used to pursue the goals of the proposal. The materials focus will be on several families of binary and ternary compounds including layered iron- and nickel-based intermetallics, half-Heusler intermetallics, hexaboride compounds, oxide materials and intercalated compounds, and other known superconducting materials. Novel synthetic techniques will be used to explore a wide phase space of such materials. These techniques include solid state synthesis, solution growth, vapor transport, and high pressure-high temperature synthesis, and will be closely coupled with combinatorial methods to allow for systematic design of optimal properties in newly synthesized materials. The fundamental physical properties of all new materials will be measured using a variety of standard and specialized techniques aimed at providing rapid and reliable feedback toward optimization of superconducting properties and understanding the potential for further discovery.

The devices focus will be on three approaches –phenomena that arise at the interface of two distinct materials, proximity effects that occur when joining superconducting, topological and magnetic multilayers, and fabrication of high-temperature topological superconductor thin films via intercalation techniques.
