Superconducting nanowires pulse to a new beat |
Superconducting nanowires pulse to a new beat (Jun 17)
http://physicsweb.org/article/news/9/6/12
Physicists in the US have made a quantum interference device by coating
a pair of DNA molecules with superconducting material. The resulting
two-nanowire device also showed unusual resistance oscillations in an
applied magnetic field (Science 308 1762).

applied magnetic field (Science 308 1762).
"'The applied magnetic field causes a small current to flow along the
trench banks, and this current then causes a large change in
resistance,' explained team member Paul Goldbart. 'The strength of the
current is controlled only by the magnetic field and the width of the
banks supporting the wires.'"
Oh boy! They've discovered a quantized single molecule field effect
transisitor. Will it cure cancer, er, AIDS?
