Abstract: Crystals are known to grow nonclassically or via four classical modes (the layer-by-layer, dislocation-driven, dendritic, and normal modes, which generally involve minimal interfacet surface diffusion). The field of nanoscience considers this framework to interpret how… read more here.

Abstract: Intervalley scattering of carriers in graphene at `top' adatoms may give rise to a hidden Kekul\'e ordering pattern in the adatom positions. This ordering is the result of a rapid modulation in the electron-mediated interaction… read more here.

DOI: 10.1103/physrevb.97.224411
Abstract: By performing ab initio calculations, we reveal an unexpected behavior of the exchange interactions between the Fe STM tip and the Fe adatom on Cu(001) and on a ${\mathrm{Cu}}_{2}\mathrm{N}$ monolayer on Cu(001) surfaces [denoted as… read more here.
