摘要：
A novel scattering-type near-field optical microscopy (s-SNOM) system based on a terahertz (THz) quantum cascade laser operating in self-detection mode is employed to probe a resonant phonon-polariton mode of a thin topological insulator flake (BizTe(2.2)Se(0.8)). Background-free near-field imaging with nanoscale spatial resolution is demonstrated.
