Electron scattering effects at physisorbed hydrogen molecules on break-junction electrodes and nanowires formation in hydrogen environment
The physisorption of hydrogen molecules on the surface of gold and other coinage metals was studied using distance tunneling spectroscopy. We observed strong N-shaped deviation of the tunnel current (resistance) vs distance dependences from the exponential one. Such deviations are difficult to exp...

| description |
The physisorption of hydrogen molecules on the surface of gold and other coinage metals was studied using
distance tunneling spectroscopy. We observed strong N-shaped deviation of the tunnel current (resistance) vs
distance dependences from the exponential one. Such deviations are difficult to explain in the framework of the
Tersoff–Hamann approximation. We suggest the scattering of the tunneling electrons by H₂ molecules as origin
for observed effect. We found that this phenomenon is also common for strongly adsorbed organic molecules
with one anchoring group. Pulling Au, Cu and Pt nanowires at 22 K in hydrogen environment show that the electrodes
of break junctions are still connected up to very low conductances of 10⁻⁴–10⁻⁶ G₀ through hydrogen–metal
one-atom chains.
