Phase-sensitive Surface Second-harmonic Generation of Topological Dirac Semimetal
We report anomalously strong, surface-specific, purely out-of-plane optical nonlinearity in PdTe 2 Dirac semimetal through polarization-dependent heterodyne-interferometric rotational-anisotropic second-harmonic generation. This strong nonlinearity is correlated to the topological surface states via surface and orbital-projected band calculations.
