Zinc oxide nanowires. Coloured scanning electron micrograph (SEM) of nanowires seen from above. Nanowires are artificially grown crystal filaments that measure only a few nanometres (billionths of a metre) in diameter,and several microns (thousandths of metres) in length. These nanowires are composed of zinc oxide (ZnO),a semiconductor material with applications in optoelectronics. ZnO nanowires could one day be used to produce miniature ultraviolet lasers,transistors,photodetectors,gas sensors and solar cells. These nanowires were created by chemist Peidong Yang and his team at the University of California,Berkeley,USA. Photographed in 2008 | |
