Ultrafast carrier interactions in metal-halide perovskites probed with two-dimensional electronic spectroscopy
We use 2D electronic spectroscopy with sub-10-fs resolution to probe carrier-carrier scattering in perovskites. We report excitation-density dependent thermalization times below 100-fs. Strong coupling with excitonic states further reveals sub-bandgap states with low oscillator strength.
