Organic field effect transistor

摘要

An organic field effect transistor including an organic semiconductor layer constituting a current path between a source electrode and a drain electrode wherein the organic semiconductor layer is made of a conjugated polymer having a depletion layer and a conductivity of the organic semiconductor layer is controlled by using a gate electrode, wherein the depletion layer is formed by joining a reductive material being capable of forming Schottky contact with the organic semiconductor layer made of the conjugated polymer. There can be provided an organic field effect transistor using a conjugated polymer as an organic semiconductor and being capable of maintaining an insulation property.
