Laser Patterning
Lightly
The deposition of thin films of
reactive metals can damage or
even melt the underlying sub-
strate. One solution to this
problem is to use a rare-gas
"buffer layer" that can absorb
and dissipate energy, and
thereby allow a cooled film to
"soft land" on the surface.
Kerner and Asscher combine
soft landing with laser-induced
thermal desorption to create
potassium nanowires that are
less than 30 nm wide and 5
mm in length on a ruthenium
substrate. Laser gratings are
