CV measurements on Mip structures of p-doped Phtalocyanine — •Jens Drechsel, Andreas Nollau, Torsten Fritz, and Karl Leo — Institut f"ur Angewandte Photophysik, TU Dresden, Germany
Organic thin film materials are widely investigated for
applications in electronic and optoelectronic devices.
We have recently shown that such materials can be doped by
strong molecular acceptors like F4-TCNQ. Here we investigate
the properties of doped organic semiconductor using
CV (capacity-voltage) spectroscopy. Very well blocking Mip
Schottky structures allow to determine spatially resolved
carrier densities and trap distributions. Frequency-dependent
measurements allow in comparision to a circuit model to
identify the relevant electronic processes.
