An electronic device including at least first and second transistors integrated together on a substrate and each including an organic semiconductor region, wherein the first and second transistors are either both n-type or both p-type but wherein one of the first and second transistors is a normally-ON transistor and the other of the first and second transistors is a normally-OFF transistor.

Organic electronic devices

A method for forming an organic or partly organic switching device. The method comprises depositing layers of conducing, semiconducting and/or insulating layers by solution processing and direct printing. Then, high-resolution patterns of electroactive polymers are formed by self-aligned formation of a surface energy barrier around a first pattern that repels the solution of a second material.

Self-aligned printing

An electronic device including first, second and third conductor layers respectively arranged as the source, drain and gate electrodes of a field effect transistor, the third conductor layer being capacitively coupled with both the first and second conductor layers but with the second conductor layer to a greater degree than with the first conductor layer, wherein the electronic device is operable as a non-linear capacitor by applying an alternating voltage across the third conductor layer and the first conductor layer whilst leaving the second conductor layer at a floating potential. Also, an electronic device including a first pair of capacitively coupled first and second conductor layers and a second pair of capacitively coupled third and fourth conductor layers, wherein the first and third conductor layers and the second and fourth conductor layers are arranged as the drain and source electrodes of respective field effect transistors together with one or more gate electrodes conductively connected to either of the first and second conductor layers, wherein the electronic device is operable as a non-linear capacitor by applying an alternating voltage across the first and second conductor layers whilst leaving the third and fourth conductor layers at a floating potential.
