Proximity-induced superconductivity in a topological crystalline insulator
Abstract
Superconducting topological crystalline insulators (TCIs) are anticipated to host new topological phases protected by crystalline symmetries, but available materials are insufficiently suitable for surface studies. To induce superconductivity at the surface of a prototypical TCI SnTe, we use molecular beam epitaxy to grow a heterostructure of SnTe and a high-T c superconductor Fe(Te,Se), utilizing a “buffer” layer to bridge the large lattice mismatch between SnTe and Fe(Te,Se). Using low-temperature scanning tunneling microscopy and spectroscopy, we measure a prominent spectral gap on the surface of SnTe, and demonstrate its superconducting origin by its dependence on temperature and magnetic field. This report offers a platform for atomic-scale investigations of emergent topological phenomena in superconducting TCIs.
