Copolymers Block Out New Approaches To Microelectronics
ScienceDaily (Mar. 17, 2008) — In response to the electronics industry's rallying cry of "smaller and faster," the next breakthroughs in the electronics size barrier are likely to come from microchips and data storage devices created out of novel materials such as organic molecules and polymers. With innovative measurement techniques and new ways to position the molecules, NIST researchers reported at the March Meeting of the American Physical Society how they have improved manipulation of so-called block copolymers--polymers made of a mixture of two or more different molecule building blocks that are tethered at a junction point--which can form arrays of tiny dots that could be used as the basis for electronic components that pack terabytes (1000 gigabytes) of memory in something as small as a pack of gum.
