Comparison between p6P thin films and nanofibers on transistor platforms

Publikation: Konferencebidrag uden forlag/tidsskriftPosterForskning

Resumé

The organic semiconductor para-hexaphenylene (p-6P) can be used as the light-emitting material in organic light-emitting field-effect transistors (OLEFETs), has a low cost, and is easy to process which could allow, for example, the development of mechanically flexible optoelectronics. In this work, a systematic investigation was made of the electrical properties of p-6P both in the form of an evaporated thin film and also in the form of nanofibers that were transferred from a template substrate (muscovite mica) onto the transistor platform. We have investigated both bottom contact, bottom gate (BC/BG) and top contact, bottom gate (TC/BG) configurations, both with gold electrodes. Thin films and nanofibers measurements showed the top contacts provide higher current (more than two orders of magnitude) than similar bottom contacts. It could be explained by the fact that for top contacts the area over which the carrier injection occurs in significantly larger compared to the bottom contact geometry.
