Abstract

A qualitative comparison between the extended disorder model for charge transport and the measured charge density dependence of the field-effect mobility is presented for field-effect transistors (see Figure) using a poly(phenylenevinylene) layer. By varying the film morphology through the use of polymers of different molecular weights, further insight into the role of morphology is gained.
