We investigate the scaling of field-effect mobility as a function of channel length in case of pentacene-based transistors with coplanar geometry. The apparent variation of mobility is mainly attributed to the effect of disorder at the metal-semiconductor interface and injection limited charge transport in case of smaller channel length. The scaling is modified using drain-source electrodes, treated with self-assembly monolayer of alkanethiol with varying carbon atoms. Copyright © 2007 Materials Research Society.

Abstract
We investigate the scaling of field-effect mobility as a function of channel length in case of pentacene-based transistors with coplanar geometry. The apparent variation of mobility is mainly attributed to the effect of disorder at the metal-semiconductor interface and injection limited charge transport in case of smaller channel length. The scaling is modified using drain-source electrodes, treated with self-assembly monolayer of alkanethiol with varying carbon atoms. Copyright © 2007 Materials Research Society.
