Full-gap superconductivity in spin-polarised surface states of topological semimetal β-PdBi2

Full-gap superconductivity in spin-polarised surface states of topological semimetal β-PdBi2

Although several materials have been proposed as topological superconductors, spin textures and superconductivity at the surface remain elusive. Here, Iwaya et al. determine the spin textures at the surface of a superconductor β-PdBi2 and find the superconducting gap opening in all spin-polarised su...
