  • A point charge near the surface of a topological insulator is predicted to generate an image magnetic charge in addition to an image electric charge as a result of electrostatic screening. We use scanning tunneling spectroscopy to study image potential states (IPS) of the topological semimetal Sb(111) surface. We observe five IPS with discrete energy levels well described by a one-dimensional model. Our investigation of the spatial variation of the IPS near surface step edges indicates an… CONTINUE READING
