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