Synthesis and superconductivity of In-doped SnTe nanostructures

摘要: InxSn1−xTe is a time-reversal invariant candidate 3D topological superconductor derived from doping the crystalline insulator SnTe with indium. The ability to synthesize low-dimensional nanostructures of indium-doped key for realizing promise they hold in future spintronic and quantum information processing applications. But hitherto only bulk synthesized crystals nanoplates have been used study superconducting properties. Here first time we including nanowires nanoribbons, which show transitions. In some lower dimensional morphologies, observe signs more than one transition absence complete superconductivity. We propose that material inhomogeneity, such as indium inhomogeneity possible impurities metal catalyst, amplified transport characteristics smaller responsible this mixed behavior. Our work represents ...
