STIR: Investigations of Candidate Topological Crystalline Insulator SnTe and Pb(1-x)Sn(x)Te
Abstract
The last five years has witness a dramatic expansion of the number of potential topological materials with a recent class of materials exploiting the crystal symmetry to create protectedstates of matter. This subset of topological materials are known as topological crystalline insulators. One candidate material, SnTe and its doped cousin Pb1-xSnxTe, offers a material system where various experimental methods of control of the topological states are possible. Further, details of the band structure potentially allow for tuning the interactions between electrons. There is excitement about exploiting these degrees of freedom in topological materials to create a panoply of novel condensed matter states, yet a definitive understanding of the topological properties of the normal and superconducting states in SnTe and Pb1-xSnxTe are lacking or unknown. Here PI Williams proposed a short, targeted study to make seminal investigations into this material to determine the nature of normal and superconducting state by employing an arsenal of measurement techniques with quantum level sensitivity. This work will provide the platform for building novel and potentially useful solid-state excitations with strong interactions in topological materials.
