Abstract
The formation of a Pd atomic chain in a hydrogen atmosphere was investigated by measurements of conductance and vibrational spectroscopy of a single molecular junction, and the theoretical calculation. While atomic chains were not formed for clean 3d and 4d metals, in the case of Pd (a 4d metal) atomic chains could be formed in the presence of hydrogen. Stable atomic chains with two different atomic configurations were formed when the Pd atomic contact was stretched in a H atmosphere; highly conductive short hydrogen adsorbed atomic chain and low conductive long hydrogen incorporated atomic chain.
