Abstract

We analyzed ultrafast photocarrier generation in single crystal CH₃NH₃PbI₃ perovskite through time-resolved terahertz spectroscopy. We find a Drude-Lorentz type conductivity spectra with a carrier mobility of 35 cm²/Vs and a Lorentzian component at 45 meV possibly due to intraexcitonic transitions.
