摘要：
Topological Insulators are band insulators in their bulk and exhibit metallic states on their surfaces characterized by a Dirac energy/momentum dispersion. In this paper we will present experimental data about Dirac plasmons in TIs as measured through terahertz (THz) spectroscopy. In particular we will discuss their frequency/momentum dispersion and their sub-ps dynamics measured by optical-pump/terahertz-probe spectroscopy.
