Photon assisted Lévy flights of minority carriers in n-InP

► Spatial distribution of minority carriers is found from photoluminescence spectra. ► The distribution shows a power-law drop-off with distance from the excitation plane. ► The photon-assisted transport is a random walk well described by the Lévy flight. ► Emission quantum efficiency of n-InP is independently determined. ► Results are in excellent agreement with earlier luminescence kinetics experiments.
