Low-temperature resistance of DNA-templated nanowires

Abstract.

We present low-temperature measurements of the electrical conductivity of metallic nanowires assembled on single DNA molecules by chemical deposition of a thin continuous palladium film. The investigated nanowires exhibit ohmic transport behaviour at room temperature. At low temperature we observe an increase of resistance with decreasing temperature that follows a logarithmic dependence. This behaviour can be described with quantum effects in a disordered metallic film.
