Observation of terahertz second harmonic generation from Dirac surface states in the topological insulator BiSe
Jonathan Stensberg, Xingyue Han, Zhuoliang Ni +6
We report the observation of second harmonic generation with high conversion efficiency in the terahertz regime from thin films of the topological insulator BiSe…
