Abstract :
This work describes the current over an interface between two different polymeric semiconductors. The interface barrier amounts to 0.7 to 1.0 eV, which is orders of magnitude larger than the thermal energy. It is demonstrated that the current across the interface is injection limited. Furthermore, it is observed that the electrical characteristics for such an organic-organic interface are completely different from those for a metal organic interface.
