Abstract

The surfaces of topological insulators contain two-dimensional massless Dirac electrons. In topological insulator thin films, electrons on the top and bottom surfaces couple. Plasmons can be excited using these coupled electrons and show resonances in the terahertz with exceptionally large mode indices and long lifetimes.
