Electric Conduction in Molecular Nanowires Dienstag, den 1.Juni, 1999, um 17.30 Uhr

Abstract:
Recent electrical measurements of two molecular nanowire model systems
will be discussed: these are carbon nanotubes and DNA. While it is known
that nanotubes can be good conductors, a surprisingly large (equilibrium)
conductivity has been found for a single (rope) of DNA attached to macroscopic
electric contacts. Nanotubes are one dimensional quantum conductors exhibiting
a large phase coherence length. However, transport is not fully ballistic
because compelling evidence for intrinsic backscattering as well as
interaction effects have been found.
