A vertical field effect transistor (FET) comprises a gate electrode and a first electrode layer having a dielectric layer interposed between these electrodes and a semiconducting active layer electrically coupled to the first electrode. The active layer and the dielectric layer sandwich at least a portion of the first electrode where at least one portion of the active layer is unshielded by the first electrode such that the unshielded portion is in direct physical contact with the dielectric layer. A second electrode layer is electrically coupled to the active layer where the second electrode is disposed on at least a portion of the unshielded portion of the active layer such that the second electrode can form electrostatic fields with the gate electrode upon biasing in unscreened regions near the first electrode.

A method of forming patterned thin films includes the steps of providing a porous membrane and a solution including a plurality of solid constituents and at least one surface stabilizing agent for preventing the solid constituents from flocculating out of suspension. The solution is dispensed onto a surface of the membrane. The solution is then removed by filtration through the membrane, wherein a patterned film coated membrane comprising a plurality of primarily spaced apart patterned regions are formed on the membrane. In one embodiment the method further includes the step of blocking liquid passage through selected portions of the membrane to form a plurality of open membrane portions and a plurality of blocked membrane portions before the dispensing step. The dispensing step includes ink jet printing the solution. An article having a patterned nanotube-including film thereon includes a substrate, and a patterned nanotube including film disposed on the substrate. The film includes a plurality of primarily spaced apart patterned regions, wherein nanotubes in the film are preferentially aligned parallel to a long direction of the patterned regions. The preferential alignment is generally most pronounced towards an edge of the patterned regions.
