Abstract
Charge carrier injection and transport in light emitting devices based on poly-phenylene-vinylene are investigated by internal photoemission and thermally stimulated currents. The barrier heights for electron injection depend very weakly on the metal work function, indicating a significant influence of surface states or interfacial layers. Trap states in PPV are detected with trap energies ranging from 0.1eV in fresh samples to 0.9eV in aged samples.
