	Diamonds are forever, aren't they? Not so, according to a new interpretation of the crystalline structure of silicon wafers. Until now, the accepted wisdom was that crystalline facets met each other at atomically sharp edges. But new research suggests that crystalline facets on the surface of silicon, gallium arsenide, glass and even diamond, are all continually changing phases in a process of rounding-off their edges. By harnessing this force at the nanoscale, Ohio State University researchers hope to enable nanowires and quantum dots to be prepatterned onto future silicon wafers.
