Low temperature dephasing in irradiated metallic wires
arXiv:0711.1810 · doi:10.1103/PhysRevB.77.033102
Abstract
We present phase coherence time measurements in quasi-one-dimensional Ag wires implanted with Ag ions with an energy of . The measurements have been carried out in the temperature range from up to ; this has to be compared with the Kondo temperature of iron in silver, i.e. , used in recent experiments on dephasing in Kondo systems\cite{mallet_prl_06,birge_prl_06}. We show that the phase coherence time is not affected by the implantation procedure, clearly proving that ion implantation process by itself \emph{does not lead to any extra dephasing} at low temperature.
