• Characterizing and modeling of exciton dissociation in polythiophene 

    Mueller, Andrew (2012-05-01)
    Exciton dissociation, the separation of an electron and hole upon excitation by radiation, is studied in the conjugated polymer polythiophene (PT). Based on data from semi-empirical simulations of exciton dissociation ...
