Direct Printing of Solution-Processed Polymer Transistor Circuits
Henning Sirringhaus *
Cavendish Laboratory, Cambridge
Polymer transistor circuits offer new opportunities for the controlled
manufacturing of active electronic circuits by a combination of solution
processing and direct printing. Control over the morphology of the
polymer semiconductor is obtained by making use of self-organisation
mechanisms, such as liquid-crystalline phase behaviour. Accurate
definition of the transistor channel and other circuit components can be
achieved by high resolution printing techniques such as surface
energy-assisted inkjet printing. We will discuss recent progress towards
new architectures for both planar-channel and vertical-channel polymer
transistors with submicrometer channel length, as well as current
understanding of charge transport and charge injection in polymer
field-effect devices. We will also give an overview over applications of
printed transistor circuits, such as active matrix displays or low-cost
radifrequency identification labels.
