▎ 摘　　要

NOVELTY - The organic thin film transistor electrode has an electrode substrate is composed of gold. A graphene oxide (6) and the electrode substrate are fixedly bonded by reaction with a selected compound. An active hydroxyl group in the graphene oxide is reactive with the reactive amino group in the selected compound. The active sulphydryl group in the selected compound is bonded to the gold of the surface of the electrode substrate. The selected compounds include mercaptoethylamine (5). USE - Organic thin film transistor electrode. ADVANTAGE - The organic thin film transistor electrode is simple in operation and can be realized by solution method in normal temperature and normal pressure environment. The system can improve the contact between the organic semiconductor and the electrode in the organic field effect transistor, and greatly improve the performance of the field effect transistor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a modification method. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the organic thin film transistor electrode.
