Abstract
Time-resolved fluorescence imaging (TR-FLIM) allows to obtain time-resolved photoluminescence maps with a micrometric resolution. We showed last year that wide-field illumination with TR-FLIM allows to observe lateral transport to a more defective zone. This study will be focused on point and structured illumination, extending the breadth of this characterization technique to bare & homogeneous absorbers. We explore this new possibility by presenting applications for a wide range of semi-conductors. By treating the datacubes with algorithms solving 2D/3D drift-diffusion equations, we derive optoelectronic properties representative for lateral diffusion and local recombination properties.
