Terahertz signatures of ultrafast Dirac fermion relaxation at the surface of topological insulators

Abstract Topologically protected surface states present rich physics and promising spintronic, optoelectronic, and photonic applications that require a proper understanding of their ultrafast carrier dynamics. Here, we investigate these dynamics in topological insulators (TIs) of the bismuth and ant...
