Scientists Observe Nanowires as They Grow (IMAGE) Karlsruher Institut für Technologie (KIT) Caption Study principle: Small thin nanowires grow on a silicon wafer after bombardment of gallium droplets with gallium and arsenic. Growth can be monitored with the help of X-rays. The fully grown nanowires were examined by electron microscopy (background).
