Experiments,stalline surfaces of semiconductor and metal are very reactive, they are readily contaminated by H.O, O., etc. in atmospheric conditions. Therefore, UHV conditions (<10. Torr) are essential to avoid contaminations from such gases and keep well-defined conditions at the atomic level. Principle and te

Water Dimer: Direct Observation of Hydrogen-Bond Exchange,ted of H-bond donor and acceptor molecule can be produced by the association of water monomers. The STM image of a dimer is characterized by an incessant fluctuation between two states. Combined with DFT calculations it is found that the fluctuation corresponds to the H-bond donor–acceptor interchan

Water Clusters: Formation of One-Dimensional Water Clusters,3–6 molecules), where water molecules are arranged along the Cu row to form a “ferroelectric” zigzag configuration, are assembled in a fully controlled fashion using the STM manipulation. H-bond rearrangements in the clusters are induced by a voltage pulse of STM. In addition to the chain configurat

Hydroxyl Group: Tunneling Dynamics of Hydrogen Atom,the STM-induced dissociation of a water molecule. A hydroxyl can be further dissociated into atomic oxygen. It is found that a hydroxyl has an inclined geometry against the surface normal and switches back and forth between the two orientations via the H atom tunneling. The switching results in the

Hydroxyl groups in a dimer have an inclined geometry in common with a monomer and flips back and forth between two states. Although the tunneling switching observed for a monomer is quenched for a dimer due to the formation of H bond between hydroxyl
