Abstract

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.
