An organic thin film transistor comprising source and drain electrodes, an organic semiconductor disposed in a channel region between the source and drain electrodes, a gate electrode, and a dielectric disposed between the source and drain electrodes and the gate electrode, wherein the source electrode and the drain electrode comprise at least one different physical and/or material property from each other.

Organic thin film transistor

An organic thin film transistor comprising: a substrate; a source electrode and a drain electrode disposed over the substrate with a channel region therebetween; a layer of organic semiconductor disposed in the channel region; a gate electrode; and a gate dielectric disposed between the layer of organic semiconductor and the gate electrode, wherein the gate dielectric comprises a cross-linked polymer and a fluorine containing polymer.

Organic thin film transistors

A method of manufacturing an organic thin film transistor, comprising: providing a substrate comprising source and drain electrodes defining a channel region; subjecting at least the channel region to a cleaning treatment step; and depositing organic semiconductive material from solution into the channel region by inkjet printing.

A method of forming an organic thin film transistor comprising source and drain electrodes with a channel region therebetween, a gate electrode, a dielectric layer disposed between the source and drain electrodes and the gate electrode, and an organic semiconductor disposed in at least the channel region between the source and drain electrodes, said method comprising: seeding a surface in the channel region with crystallization sites prior to deposition of the organic semiconductor; and depositing the organic semiconductor onto the seeded surface whereby the organic semiconductor crystallizes at the crystallization sites forming crystalline domains in the channel region.

An organic thin film transistor, and a method of making the same, comprising a source and drain electrode and organic semi-conductive material disposed therebetween in a channel region, in which the source and drain electrodes have disposed on them a thin self-assembled layer of a material comprising a dopant moiety for chemically doping the organic semi-conductive material by accepting electrons, the dopant moiety having a redox potential of at least 0.3 eV relative to a saturated calomel electrode in acetonitrile.

Organic thin film transistors and methods of making the same

A method of forming an optical device comprising the steps of: providing a substrate comprising a first electrode capable of injecting or accepting charge carriers of a first type; forming over the first electrode a first layer that is at least partially insoluble in a solvent by depositing a first semiconducting material that is free of cross-linkable vinyl or ethynyl groups and is, at the time of deposition, soluble in the solvent; forming a second layer in contact with the first layer and comprising a second semiconducting material by depositing a second semiconducting material from a solution in the solvent; and forming over the second layer a second electrode capable of injecting or accepting charge carriers of a second type wherein the first layer is rendered at least partially insoluble by one or more of heat, vacuum and ambient drying treatment following deposition of the first semiconducting material.
