Abstract: The interaction and mobility of ions in complex systems are fundamental to processes throughout chemistry, biology, and physics. However, nanoscale characterization of ion stability and migration remains poorly understood. Here, we examine ion movements to… read more here.

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.
