A novel polymer as a functional dielectric layer for OTFTs to improve the grain size of the pentacene semiconductor
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.
