The unexpected metal

Nature Materials

2008년6월16일

Placing two different organic insulators in contact creates a metallic channel at the interface, resulting in the formation of new electronic states, reports a study online this week in Nature Materials. These electronic states are not achievable in the bulk material and provide new ways of researching organic electronics.

Alberto Morpurgo and colleagues used a simple technique to bring the organic crystals known as TTF and TCNQ in direct mechanical contact. These crystals are very good insulators, but when placed next to each other, electrons from TTF can transfer to TCNQ thus creating a population of mobile electronic charges.

As Jochen Mannhart discusses in a linked News & Views article, these results promise new routes for research in organic electronics.
