Single-molecule electronic wires created

[i][b]PITTSBURGH, Sept. 27 (UPI) -- U.S. scientists have created a template for assembling advanced, single-molecule-based electronic components.[/b][/i]vWNv,Ue-y(Y$H
University of Pittsburgh researchers said their achievement is a significant step in science's increasing attempts to reduce electronic device circuitry to a single molecule scale to provide smaller, faster, and more energy efficient electronics.V*yFh}`V
Led by physics Professor Hrvoje Petek, the scientists created a template for assembling molecules over troughs that are only as wide as a single atom of copper, but can be made several times that length, matching wires currently used in computers and other devices. The researchers said the ultra-thin, one-dimensional wires might be able to conduct electricity with minimal loss and thus improve the performance of an electronic device.
Q?2N0P:St+@X Petek said the research pertains to carbon molecules known as fullerenes, but the method can serve as a template for a broad range of organic molecules.%e9Sj9]vK0L
Materials used in contemporary electronics, such as silicon, are inorganic and cannot be miniaturized to be truly one-dimensional, Petek said.
