Abstract
The measurement and analysis of the current-voltage characteristics of a liquid-crystalline organic semiconductor 2-(4'-Octyphenyl)-6-dodecyloxynaphthalene (8-PNP-O12) in contact with electrodes of Pt, Au, ITO, Cr, and Al in the order of work function revealed that the injection of positive holes from the electrodes of Pt, Au, and ITO to 8-PNP-O12 took place according to the Schottky model, and that an electric double layers was formed at the interface between each of these electrodes and 8-PNP-O12, making it difficult to inject positive holes from the former to the latter.
