Anisotropic surface-state-mediated RKKY interaction between adatoms

January 18, 2012

Author(s)

Paul N. Patrone, T L. Einstein

Motivated by recent numerical studies of Ag on Pt(111), we derive a far-field expression for the RKKY interaction mediated by surface states on a (111) FCC surface. The main contribution to the interaction comes from electrons whose Fermi velocity is

Small fluctuations in epitaxial growth via conservative noise

July 7, 2011

Author(s)

Paul N. Patrone, Rongrong Wang, Dionisios Margetis

We study the combined effect of growth (material deposition from above) and nearest-neighbor entropic and force-dipole interactions in a stochastically perturbed system of N line defects (steps) on a vicinal crystal surface in 1+1 dimensions. First, we
