'Explosive' atom movement is new window into growing metal nanostructures

'Explosive' atom movement is new window into growing metal nanostructures

Scientists at the US Department of Energy's Ames Laboratory expected to see slow, random movement when they dropped lead atoms on a lead-on-silicon surface. 'But what we saw? BOOM! Fast, explosive and organized!' said Michael Tringides, Ames Laboratory physicist. The unusual atom movement may represent a new way to grow perfect, tiny metal nanostructures for nanostransistors, nanoswitches, and nanomagnets.

Breakthrough: Nanote creates more electron beam than large laser system

A collaboration led by RadiaBeam Technologies, a California-based technology firm actively involved in accelerator R&D, is designing an electron beam source that doesn't need a laser. The team led by Luigi Faillace, a scientist at RadiaBeam, is testing a carbon nanotube cathode -- about the size of a nickel -- in Fermilab's High-Brightness Electron Source Lab that completely eliminates the need for a room-sized laser system currently used to generate the electron beam.
