Theoretical aspects of vertical and lateral manipulation of atoms
Chandana Ghosh, Abdelkader Kara, Talat S. Rahman
Using total energy calculations, based on interaction potentials from the embedded atom method, we show that the presence of the tip not only lowers the barrier for lateral diffusi…
Phonons of Metallic Vicinal Surfaces
Abdelkader Kara, Talat S. Rahman
We present an analysis of the vibrational dynamics of metal vicinal surfaces using the embedded atom method to describe the interaction potential and both a real space Green's func…
Electronic Structure of the c(2x2)O/Cu(001) System
Sergey Stolbov, Abdelkader Kara, Talat S. Rahman
The locally self-consistent real space multiple scattering technique has been applied to calculate the electronic structure and chemical binding for the c(2x2)O/Cu(001) system, as…
Ab initio Calculations of Multilayer Relaxations of Stepped Cu Surfaces
Rolf Heid, Klaus Peter Bohnen, Abdelkader Kara +1
We present trends in the multilayer relaxations of several vicinals of Cu(100) and Cu(111) of varying terrace widths and geometry. The electronic structure calculations are based o…
