Is Au/Ge(001) a model system for a 1D Electron Liquid? — Arie van Houselt, Daan Kockmann, Tijs Mocking, Bene Poelsema, and •Harold Zandvliet — MESA+ instute for Nanotechnology and University of Twente, Enschede, The Netherlands

Recently it has been claimed that the Au induced nanowires on Ge(001) represent an outstanding case for a one-dimensional electron liquid [1]. Here we show, based on the data of the authors of ref. [1], that the differential conductivity of the Au induced nanowires and the troughs between the nanowires are comparable in magnitude [2]. Therefore, this system cannot be considered as a model system for a one-dimensional electron liquid [2-4].
