Manipulation of Organic Molecules in Ambient Condition and Liquid Studied by Scanning Tunneling Microscopy

Scanning tunneling microscopy manipulation of complex organic molecules on solid surfaces.

Organic molecules adsorbed on solid surfaces display a fascinating variety of new physical and chemical phenomena ranging from self-assembly and molecular recognition to nonlinear optical properties and current rectification. Both the fundamental interest in these systems and the promise of technological applications have motivated a strong research effort in understanding and controlling these...

Metal-silicene interaction studied by scanning tunneling microscopy.

Ag atoms have been deposited on 3  ×  3 silicene and  √3  ×  √3 silicene films by molecular beam epitaxy method in ultrahigh vacuum. Using scanning tunneling microscopy and Raman spectroscopy, we found that Ag atoms do not form chemical bonds with both 3  ×  3 silicene and  √3  ×  √3 silicene films, which is due to the chemically inert surface of silicene. On 3  ×  3 silicene films, Ag atoms mo...

Direct Determination of the Chirality of Organic Molecules by Scanning Tunneling Microscopy

Scanning tunneling microscopy (STM) has been used to study the chiral molecules (R)/(S)-2-bromohexadecanoic acid at the liquid/solid interface. When adsorbed onto the basal plane of graphite, these molecules segregate on the surface into domains of pure R or S enantiomers. The atomic resolution obtained in the STM images of these species allows a direct assignment of the chirality of individual...
