Helical Nanobelts Roll Up for Devices

nanotechweb.org News, 7 Apr 2005 Researchers at the Paul Scherrer Institute and the University of Basel, both in Switzerland, have worked out how to control the formation of helical nanobelts from strips of semiconductor. The scientists found they could tailor the design of the spirals by altering parameters such as the width of the belt, its crystal direction and the shape of its tip. Read the article
