Nanowires on nickel, SEM
Nanowires on nickel. Coloured scanning electron micrograph (SEM) of nanowire structures formed on a nickel surface by pulses of a laser beam. This research involves the use of lasers to etch and ablate metal and semiconductor surfaces. The resulting nanostructures can have applications in various forms of electronics and nanotechnology., by GEORGY SHAFEEV/SCIENCE PHOTO LIBRARY
