Electron Transport Properties of Au, Ag, and Cu Atomic Contacts in a Hydrogen Environment Tomoka Nakazumi, Satoshi Kaneko, and Manabu Kiguchi* Department of Chemistry, Graduate School of Science and Engineering, Tokyo Institute of Technology 2-12-1 W4-10 Ookayama, Meguro-ku, Tokyo 152-8551, Japan ABSTRACT: This study investigates the electron transport properties of Au, Ag and Cu atomic contacts in a hydrogen environment at 10 K, by using the mechanically controllable break junction (MCBJ) technique. A sharp 0.2 G0 (2e2/h) peak was observed in the conductance histogram of H2/Cu contacts, whereas a low conductance tail (
