Reaching For The Limits of Tiny Transistors

Computer chip makers have long struggled to build ever-smaller transistors to allow faster, more powerful computers. Writing in the journal Nature Natotechnology, a team of scientists describes what may be the ultimate limit of that struggle — a transistor made of a single atom. Michelle Simmons, a physicist at the University of New South Wales in Australia and leader of the project, discusses the work.
