CH(3)NH(3)PbI(3) perovskite single crystals: surface photophysics and their interaction with the environment

Here we identify structural inhomogeneity on a micrometer scale across the surface of a CH(3)NH(3)PbI(3) perovskite single crystal. At the crystal edge a local distortion of the crystal lattice is responsible for a widening of the optical bandgap and faster photo-carrier recombination. These effects...
