|Title:||Stability of face-centered cubic and icosahedral lead clusters||Authors:||H.S. Lim
|Issue Date:||15-May-1992||Citation:||H.S. Lim,C.K. Ong,Ercolessi, F. (1992-05-15). Stability of face-centered cubic and icosahedral lead clusters. Surface Science 269-270 (C) : 1109-1115. ScholarBank@NUS Repository.||Abstract:||The relative stability of relaxed icosahedral and cubotahedral lead clusters has been determined by computing their binding energies, using an empirical many-body Hamiltonian fitted on bulk and surface properties of Pb. Face-centered structures are found to be favoured over icosahedral structure for all cluster sizes. We present a qualitative explanation of this somewhat unexpected result, connected with the low surface energy anisotropy and the large tensile surface stress on Pb surfaces. © 1992.||Source Title:||Surface Science||URI:||http://scholarbank.nus.edu.sg/handle/10635/98010||ISSN:||00396028|
