Organic nanoelectronics a step closer

Quebec | Posted on June 17th, 2010

Although they could revolutionize a wide range of high-tech products such as computer displays or solar cells, organic materials do not have the same ordered chemical composition as inorganic materials, preventing scientists from using them to their full potential. But an international team of researchers led by McGill's Dr. Dmitrii Perepichka and the Institut national de la recherche scientifique's Dr. Federico Rosei have published research that shows how to solve this decades-old conundrum. The team has effectively discovered a way to order the molecules in the PEDOT, the single most industrially important conducting polymer.

Although Dr. Perepichka is quick to point out that the research is not directly applicable to products currently in the market, he gives the example of a possible use for the findings in computer chips. "It's a well known principle that the number of transistors in a computer chip doubles every two years," he said, "but we are now reaching the physical limit. By using molecular materials instead of silicon semiconductor, we could one day build transistors that are ten times smaller than what currently exists." The chips would in fact be only one molecule thick.

The technique sounds deceptively simple. The team used an inorganic material - a crystal of copper - as a template. When molecules are dropped onto the crystal, the crystal provokes a chemical reaction and creates a conducting polymer. By using a scanning probe microscope that enabled them to see surfaces with atomic resolution, the researchers discovered that the polymers had imitated the order of the crystal surface. The team is currently only able to produce the reaction in one dimension, i.e. to make a string or line of molecules. The next step will be to add a second dimension in order to make continuous sheets ("organic graphite") or electronic circuits.

Perepichka is affiliated with McGill University's department of chemistry and Rosei is affiliated with Institut national de la recherche scientifique - Énergie Matériaux Télécommunications Center, a member of the Université du Québec network. Their research was published online by the Proceedings of the National Academy of Sciences and was funded by the Natural Sciences and Engineering Research Council of Canada, the Air Force Office of Scientific Research and Asian Office of Aerospace Research and Development of the USA, the Petroleum Research Fund of the American Chemical Society, the Fonds québécois de recherche sur la nature et les technologies, and the Ministère du Développement économique, de l'Innovation et de l'Exportation of Quebec.
