Gallium nitride nanowires, SEM
Gallium nitride nanowires, coloured scanning electron micrograph (SEM). Nanowires, seen here grown in square plots, 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 gallium nitride (GaN), a semiconductor material with applications in optoelectronics. GaN nanowires could one day be used to produce miniature circuits, amplifiers, blue LEDs, ultraviolet lasers and detectors. 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 the intricate beauty of gallium nitride nanowires, as captured by a scanning electron microscope (SEM). These artificial crystal filaments, grown in square plots, possess an astonishingly small diameter of just a few nanometres and can reach lengths of several microns. The composition of these nanowires is gallium nitride (GaN), a semiconductor material with vast potential in the field of optoelectronics. The applications for GaN nanowires are truly groundbreaking. They hold the promise to revolutionize various technologies by enabling the production of miniature circuits, amplifiers, blue LEDs, ultraviolet lasers, and detectors. This extraordinary image was brought to life by chemist Peidong Yang and his team at the University of California, Berkeley in 2008. The false-colored SEM image not only captures the scientific marvel that is gallium nitride nanowires but also serves as a testament to human ingenuity and innovation in materials science. It represents our relentless pursuit to push boundaries and explore new frontiers in technology. As we delve deeper into the realm of nanotechnology and semiconductors, images like this remind us that even on such minuscule scales, there exists immense potential for advancements that could shape our future. The possibilities offered by these tiny structures have sparked excitement within scientific communities worldwide. This photograph from Science Photo Library encapsulates both artistic elegance and cutting-edge research while providing us with a glimpse into what lies ahead for electronics and photonics industries.
