Island Shape Controls Magic-Size Effect for Heteroepitaxial Diffusion
Henry H. Wu, A. W. Signor, Dallas R. Trinkle
Lattice mismatch of Cu on Ag(111) produces fast diffusion for special "magic sizes" of islands. A size- and shape-dependent reptation mechanism is responsible for low diffusion bar…

Misfit-Dislocation-Mediated Heteroepitaxial Island Diffusion
A. W. Signor, Henry H. Wu, Dallas R. Trinkle
Scanning tunneling microscopy combined with molecular dynamics simulations reveal a dislocation-mediated island diffusion mechanism for Cu on Ag(111), a highly mismatched system. C…

Cu/Ag EAM Potential Optimized for Heteroepitaxial Diffusion from ab initio Data
Henry H. Wu, Dallas R. Trinkle
A binary embedded-atom method (EAM) potential is optimized for Cu on Ag(111) by fitting to ab initio data. The fitting database consists of DFT calculations of Cu monomers and dime…
