Abstract

We use ultrafast transient absorption microscopy to map the effect of structural disorder on the photophysical properties within a micrometer-sized crystal of methylammonium lead iodide (CH 3 NH 3 PbI 3 ) perovskite. We reveal a spatial inhomogeneity of the structural and photophysical behavior on the submicrometer scale induced by a local distortion of the crystal lattice, which affects the electron–hole correlation over the hundreds of nanometers length scale.
