Anomalous Decay of Electronically Stabilized Lead Mesas on Ni(111)\ud [PDF]

, 2011
With their low surface free energy, lead films tend to wet surfaces. However, quantum size effects (QSE) often lead to islands with distinct preferred heights. We study thin lead films on Ni(111) using low energy electron microscopy and selected area low
