Nanotube enabled thin film transistors utilizing low mobility organic semiconductors.

Abstract

We describe a novel organic thin film transistor architecture enabled by single walled carbon nanotubes. Initial devices exhibit 2 orders of magnitude current modulation at useful currents despite the use of low mobility organic semiconductors (that exhibit no detectable current in a conventional TFT architecture). Modeling shows that the present devices function principally via Shottky barrier modulation, however as the source drain distance is reduced bulk modulation should also occur, with corresponding improvements in performance.
