Ultrafast carrier thermalization in lead iodide perovskite probed with two-dimensional electronic spectroscopy
Abstract
Carrier-carrier scattering rates determine the fundamental limits of carrier transport and electronic coherence. Using two-dimensional electronic spectroscopy with sub-10 fs resolution, Richter and Branchi et al. extract carrier thermalization times of 10 to 85 fs in hybrid perovskites.
