The importance of relativistic effects on two-photon absorption spectra in metal halide perovskites
Metal halide perovskites possess interesting properties but their sub-bandgap absorption remains largely unexplored. Here Wei et al. employ two-photon absorption spectroscopy with time-resolved microwave conductivity technique to confirm the existence of strong spin-orbit coupling effect.
