Limitations of Mott-Schottky Analysis for Organic Metal-Insulator-Semiconductor Capacitors

摘要

The application of Mott-Schottky (MS) relation in organic devices often leads to erroneous results. In particular, the doping density, extracted using this method found to vary with the thickness of semiconductor. We address the limitations in using MS relationship for organic metal-insulator-semiconductor (MIS) capacitors as a consequence of deviation from the depletion approximation.
