Carrier effective masses. Effective masses of electrons and holes in the cubic (red) and tetragonal (blue) MAPbI3 phases versus the band gap, shown for 10 structures (in each phase) that differ only for their MA random alignment. The dotted line given for comparison is the electron effective mass of GaAs. The LDA band gaps were shifted by ~1.2 eV to match the experimental gap
