Transport Calculations for Si4 Clusters with Gold single Atom Contacts — •Jeffrey Kelling1, Jochen Kerbusch1,2, Artur Erbe1, Rainer Dietsche3, Gerd Ganteför3, Elke Scheer3, Peter Zahn1, and Sibylle Gemming1,4 — 1Institute of Ion Beam Physics and Materials Research, Helmholtz-Zentrum Dresden-Rossendorf, Dresden, Germany — 2Center for Advancing Electronics Dresden (CFAED), Technische Universität Dresden, Dresden, Germany — 3Physics Department, University of Konstanz, Konstanz, Germany — 4Institute of Physics, TU Chemnitz, Chemnitz, Germany
We present results for electronic transport through Si4 clusters contacted by single-atom gold contacts attached to <111> fcc-gold leads. The calculations were performed using density functional theory and the non-equilibrium Green’s function approach for transport. The simulation setup mimics contacts in mechanically controllable break-junction experiments, which provide data for comparison.
