Structural Control of Atomic Silicon Wires
Furkan M. Altincicek, Christopher C. Leon, Lucian Livadaru +5
Bare Si(100)-21 surface atoms exhibit a buckled structure where one Si atom in a dimer is lowered while the other is raised, leading to two possible buckling configurations…
Electronic Structures of Atomic Silicon Dimer Wires as a Function of Length
Furkan M. Altincicek, Lucian Livadaru, Christopher C. Leon +6
Bare silicon dimers on hydrogen-terminated Si(100) have two dangling bonds. These are atomically localized regions of high state density near to and within the bulk silicon band ga…
Scanning Tunneling Microscopy for Molecules: Manipulating Electron Transport through the Conduction Gap by varying Buffer Layer
Abhishek Grewal, Christopher C. Leon, Olle Gunnarsson
In scanning tunneling microscopy of molecules, an insulating buffer layer is often introduced to reduce interactions between adsorbed molecules and the substrate. Focusing on tunne…
Scanning Tunneling Microscopy for Molecules: Effects of Electron Propagation into Vacuum
Abhishek Grewal, Christopher C. Leon, Klaus Kuhnke +2
Using scanning tunneling microscopy (STM), we experimentally and theoretically investigate isolated platinum phthalocyanine (PtPc) molecules adsorbed on atomically thin NaCl(100) v…
Anionic Character of the Conduction Band of Sodium Chloride
Christopher C. Leon, Abhishek Grewal, Klaus Kuhnke +2
The alkali halides are ionic compounds. Each alkali atom donates an electron to a halogen atom, leading to ions with full shells. The valence band is mainly located on halogen atom…
Character of electronic states in the transport gap of molecules on surfaces
Abhishek Grewal, Christopher C. Leon, Klaus Kuhnke +2
We report on scanning tunneling microscopy (STM) topographs of individual metal phthalocyanines (MPc) on a thin salt (NaCl) film on a gold substrate, at tunneling energies within t…
