image: Three parallel memory bits with carbon nanotube electrodes (false color image based on topographic profile from atomic force microscopy). The middle bit is in the “off” state, with blue carbon nanotube electrodes, the other bits are “on”. The silicon dioxide substrate is shown in a lighter shade of blue. This image relates to an article that appeared in the March 10, 2011, issue of Science Express, published by AAAS. The study, by Dr. Feng Xiong, at University of Illinois, Urbana-Champaign in Urbana-Champaign, Ill., and colleagues was titled, "Low Power Switching of Phase Change Materials with Carbon Nanotube Electrodes." view more
