Organic field effect transistors are receiving increased attention during the last few years due to their potential application in low cost electronics. It has been proven that grain boundaries significantly influence charge transport in these devices. In order to evaluate the maximum performance that can be achieved for a certain type of organic molecule, it is thus necessary to investigate the charge carrier transport in single crystalline devices.
We have studied the field effect in organic single crystals. The crystals were grown by a sublimation technique in a stream of vapor. We have investigated the influence of different organic materials (Tetracene, Anthracene), different gate insulators (Mylar, PPX) and different electrode materials (silver paste, colloidal graphite) on the field effect.
