Abstract

Abstract : A series of novel polymers as functional dielectric layers for pentacene thin-film transistors was synthesized and investigated to explore the relationship between the grain size and the charge carrier mobility with a single variable. Abstract : In this paper, we report the design, synthesis, and dielectric properties of novel polymers as functional dielectric layers in pentacene thin-film transistors (TFTs) to explore the relationship between the grain size and the charge carrier mobility with a single variable. The polymers were synthesized with a novel monomer, anthracen-10-ylmethyl methacrylate (A-10-YMA), that contained anthracene, which provided a crystal nucleus for the crystallization of pentacene. Increasing the amount of the novel monomer in the polymer structure resulted in a significant decrease in the grain size of the pentacene semiconductor. The result illustrates that pentacene TFTs with a suitable grain size of the pentacene semiconductor exhibit an excellent performance in terms of the charge carrier mobility.
