| This gallery exhibits scanning electron microscope images of silicon micro- and nano-structures which were formed upon solidification of a highly-doped silicon wafer. The silicon was locally melted (at about 1400 degrees Celsius, or 2600 degrees Farenheit) by passing an electric current through a suspended section of the wafer, and then rapidly solidified. The intricate "frozen" geometries formed by competition of surface tension forces and crystallization forces. |
| These images will be featured in the February/March 2007 issue of SEED magazine. |
