Formation and characterization of the stable single atomic and molecular junction

我们在电化学电位控制下制备了稳定的金属原子线。金属丝的结构和稳定性可以通过电化学电位来控制。发展了具有新的金属-分子接触的单分子结，如Au-CN、Pt-CN、Pt-S键。为了表征单分子结，我们发展了单分子结的振动光谱。利用该光谱对氢分子和苯分子的连接进行了表征。

We have fabricated stable metal atomic wires under the electrochemical potential control. The structure and stability of the wire can be controlled by the electrochemical potential. The single molecular junctions having new metal-molecule contact was developed, such as Au-CN, Pt-CN, Pt-S bonds. In order to characterize the single molecular junction, we developed the vibration spectroscopy of the single molecular junction. The hydrogen and benzene molecular junction was characterized with this spectroscopy.
