Abstract:
Various examples are provided for ambipolar vertical field effect transistors (VFETs). In one example, among others, an ambipolar VFET includes a gate layer; a source layer that is electrically percolating and perforated; a dielectric layer; a drain layer; and a semiconducting channel layer. The semiconducting channel layer is in contact with at least a portion of the source layer and at least a portion of the dielectric layer and the source layer and the semiconducting channel layer form a gate voltage tunable charge injection barrier. Another example includes an ambipolar vertical field effect transistor including a dielectric surface treatment layer. The semiconducting channel layer is in contact with at least a portion of the source layer and at least a portion of the dielectric surface treatment layer and where the source layer and the semiconducting channel layer form a gate voltage tunable charge injection barrier.
Abstract:
A method is provided for preparing a printed metal surface for the deposition of an organic semiconductor material. The method provides a substrate with a top surface, and a metal layer is formed overlying the substrate top surface. Simultaneous with a thermal treatment of the metal layer, the metal layer is exposed to a gaseous atmosphere with thiol molecules. In response to exposing the metal layer to the gaseous atmosphere with thiol molecules, the work function of the metal layer is increased. Subsequent to the thermal treatment, an organic semiconductor material is deposited overlying the metal layer. In one aspect, the metal layer is exposed to the gaseous atmosphere with thiol molecules by evaporating a liquid containing thiol molecules in an ambient air atmosphere.
