TINY TWISTER
Trucks drive over the Golden Gate Bridge with little effect, but a
proposed nanoscale bridge would shudder even from the flow of
electrons. The device, described theoretically in the 2 September
PRL, would detect the electrons' spins by measuring the bridge's tilt
as the electrons traverse it. Running it backward by forcing the
bridge to tilt could generate a current of electrons with aligned
spins. The device could be an essential component in the emerging
field of spintronics--electronics that manipulate electron spins in
addition to charges--which may someday transform information
technology and computing.
