Charge Density and Film Morphology Dependence of Charge Mobility in Polymer Field-Effect Transistors

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 po...

Description
Summary: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.
