Abstract

Organic thin film transistors for display applications are investigated. Different dielectric materials – inorganic and organic – have been studied with respect to their electrical performance It was found that anodic oxidation is an excellent process to achieve smooth high-k dielectrics with high breakthrough field strength. With the proposed electrolyte electrical properties were further improved. The alignment of pentacene on different insulators as well as transistors characteristics is presented.
