Topological phase transitions and charge-spin transport in vdW-molded bismuth

Abstract

Our research objective is to study the electronic and spintronic properties of thin bismuth crystals. Our unique technical approach is to grow the bismuth crystals inside nanoscale molds that are smooth on the atomic-scale, resulting in flat and thin crystals with improved properties. The outcomes of this research will be an understanding of how electricity conducts through the surfaces and edges of thin bismuth crystals, and how electrical currents in bismuth can both generate spin magnetism and control spin quantum bits. We will also investigate how our novel growth technique can be applied to other metals with low melting points. The impact of this research comes from the potential of bismuth to enable new types of spintronic and quantum spin devices, which is important for energy-efficient computation and the realization of highly-sensitive quantum sensors.
