Abstract

The invention discloses a low-voltage organic thin-film transistor and a preparation method thereof, belonging to the technical field of organic electronics. The organic thin-film transistor comprises an insulating substrate, a gate electrode on the insulating substrate, gate dielectrics covering the insulating substrate and the gate electrode, a source electrode and a leakage electrode on the gate dielectric and organic semiconductor layers covering the gate dielectric, the source electrode and the leakage electrode. The preparation method comprises the steps of: firstly, preparing the gate electrode on the insulating substrate; secondly, preparing dielectric layers on the surfaces of the insulating substrate and the gate electrode; then, preparing the source electrode and the leakage electrode on the dielectric layers; and finally, depositing the organic semiconductor layers on the dielectric layer, the source electrode and the leakage electrode to complete the preparation of the device. In the invention, by utilizing an atomic layer deposition method, thinner metallic oxide films are prepared to serve as the dielectric layers and the capacitance of the organic thin-film transistor device is greatly increased, therefore, the voltage of the device is reduced and the organic thin-film transistor with low working voltage can be obtained.
