Abstract
We report conducting atomic force microscopy study of nanoscale hole transport in an electroluminescent polymer. Imaging of current variation with a spatial resolution of around 20 nm is achieved. Local current–voltage measurements are performed and the mobilities obtained from space-charge-limited current analysis are two orders of magnitude higher than macroscopic results. A Poole–Frenkel plot shows a clear transition at a field of around 1.5×106 V/cm, which is consistent with reported values of polaron dissociation field.
