Carrier mobility is a basic semiconductor property. Manteet al., use femtosecond lasers to investigate coherent acoustic phonons and relate their deformation potentials to estimate the intrinsic electron and hole mobilities of CH3NH3PbI3 single crystals to be 2,800 and 9,400 cm2 V−1 s−1, respectively.
