Zinc oxide nanowires, SEM
Zinc oxide nanowires, coloured scanning electron micrograph (SEM). 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 zincoxide (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

EDITORS COMMENTS
This print showcases zinc oxide nanowires, captured using a scanning electron microscope (SEM). These nanowires are artificially grown crystal filaments that possess an incredibly small diameter of just a few billionths of a meter, while stretching several thousandths of meters in length. Composed of zinc oxide (ZnO), which is a semiconductor material with immense potential in optoelectronics, these nanowires hold promise for various applications. Chemist Peidong Yang and his team at the University of California, Berkeley were responsible for creating these remarkable nanowires back in 2008. Their groundbreaking work has paved the way for future advancements in microengineering and technology. With their unique properties, ZnO nanowires could revolutionize industries by enabling the production of miniature ultraviolet lasers, transistors, photodetectors, gas sensors, and solar cells. The intricate structure and composition of these nanowires make them ideal candidates for further exploration within the field of materials science. As researchers delve deeper into this fascinating realm known as nanotechnology, they aim to unlock even more possibilities for utilizing ZnO nanowires in areas such as nano photovoltaics and photonics. This mesmerizing image serves as a testament to human ingenuity and innovation on the microscopic scale. It reminds us that progress knows no bounds when it comes to pushing boundaries within scientific discovery.
