Vertical channel organic field effect transistor and method for producing the same

Abstract

The invention discloses a vertical channel organic field effect transistor, and belongs to the field of organic microelectronics. The structure of the vertical channel organic field effect transistor comprises a metal source electrode at an insulating substrate, a gate dielectric layer, an insulating layer, an organic semiconductor layer, a gate electrode and a metal drain electrode, wherein, the long strip-shaped gate electrode is surrounded at the exact center of the device by the dielectric layer and the organic semiconductor material; both the source electrode and the drain electrode are planar electrodes, and by changing the direction of the channel from horizontal direction to vertical direction, the length of the channel can be effectively controlled only by controlling the growth thickness of a thin film, thus avoiding the expensive electron beam lithography, and providing a simple and convenient and low-cost method for preparing a short-channel organic field effect transistor. A method for preparing the vertical channel organic field effect transistor is also provided.
