Diffusion and binding of CO on Pt nanowires

The diffusion and binding of CO molecules on self organized Pt nanowires on Ge(0 0 1), have been studied by room temperature scanning tunneling microscopy. CO molecules are found to bind at the bridge position of the Pt dimers. The CO molecules are mobile at room temperature and perform an “unrestri...

Description
Summary:	The diffusion and binding of CO molecules on self organized Pt nanowires on Ge(0 0 1), have been studied by room temperature scanning tunneling microscopy. CO molecules are found to bind at the bridge position of the Pt dimers. The CO molecules are mobile at room temperature and perform an “unrestricted” one-dimensional random walk in defect-free regions of the Pt nanowires.
