Proximity induced ferromagnetism, superconductivity, and finite-size effects on the surface and edge states of topological insulator nanostructures

Parijat Sengupta, Tillmann Kubis, Yaohua Tan +1

Bi${}_2$Te${}_3$ and Bi${}_2$Se${}_3$ are well known 3D-topological insulators. Films made of these materials exhibit metal-like surface states with a Dirac dispersion and possess…
