Electronic transport analysis in a molecular doped polymer based on dispersive-trapping formalism

The spatio-temporal spreading features of charge packets from Time of Flight (TOF) current transients in a Molecular Doped Polymer (MDP) system are analyzed. The experimental results relate to the thermal and electric field prominant dependencies of the dispersion parameters besides the charge carrier mobility. The parameters describing the charge spatial spread are the velocities distributions within the moving packet, trapping time and others. These parameters supplement our understanding about charge transport in these systems in addition to what has already been acquired from mobility investigations previously.
