Strong nonlinear terahertz response induced by Dirac surface states in Bi2Se3 topological insulator
Electrons with a linear energy/momentum dispersion are called massless Dirac electrons and represent the low-energy excitations in exotic materials such as graphene and topological insulators. Dirac electrons are characterized by notable properties such as a high mobility, a tunable density and, in...
