Coexistence of Surface Superconducting and Three-Dimensional Topological Dirac States in Semimetal KZnBi

Coexistence of Surface Superconducting and Three-Dimensional Topological Dirac States in Semimetal KZnBi

We report the discovery of a new three-dimensional (3D) topological Dirac semimetal (TDS) material KZnBi, coexisting with a naturally formed superconducting state on the surface under ambient pressure. Using photoemission spectroscopy together with first-principles calculations, a 3D Dirac state wit...
