Abstract:
1. An organic field-effect transistor comprising: source and drain electrodes; a semiconductor layer made of an organic semiconductor material placed at least between said source and drain electrodes; a gate electrode suitable for creating an electric field said electric field in turn increasing the density of mobile charge carriers in the semiconductor layer in order to create a conduction channel in said semiconductor layer between the source and drain electrodes when a voltage V an electrical insulator layer interposed between the gate electrode and the semiconductor layer, characterized in that said organic field-effect transistor further includes a piezoelectric layer proximate to the conduction channel in the semiconductor layer between the source and drain electrodes, or on the opposite side of the gate electrode with respect to the electrical insulator and semiconductor layers and alongside the source and drain electrodes, said piezoelectric layer being electrically isolated from said source and drain electrodes and from the semiconductor layer.
