Abstract

We present an approach to inkjet print high-performance organic transistors by printing the organic semiconductor ink on a thin, continuous, and solvent-absorbing layer of insulating material. The ink spreading is effectively controlled by local dissolution of the layer, and during drying the characteristic circular morphology with high rims and inner plateau forms.
