C. J. Muller, M. A. Reed
The ability to manipulate matter atom by atom offers possibilities for new electronic devices and for studying new physical phenomena. In their Perspective, Muller and Reed discuss recent experiments in which current flows between contacts made from individual atoms. Such structures may be applicable in new sensor technologies.
