Polythiophene mesowires: synthesis by template wetting and local electrical characterisation of single wires
Abstract
We report on the synthesis of semiconducting mesowires from regioregular poly(3-hexylthiophene) via melt injection into a porous alumina template. Following liberation from the template, mesowires with diameters ∼450 nm and average lengths of 10 µm were obtained. For two-terminal electrical contacting of individual mesowires on insulating substrates, the drain electrode was formed by shadow masking and
