Growing organic semiconductors on S L dielectrics with different surface energies and dielectric constants results in striking changes of the film morphology (Figure, right). Ambipolar transport is reported in pentacene transistors on a PVA gate dielectric (left). The current-voltage characteristics correlate with capacitance-voltage investigations on metal-insulator-semiconductor structures.
