Lead clusters: different potentials, different structures
Jonathan P.K. Doye
TL;DR
This paper investigates the lowest-energy structures of lead clusters with fewer than 151 atoms using a Gupta potential, revealing size-dependent structural preferences and differences from previous studies with a lead glue potential.
Contribution
It provides new insights into lead cluster structures using the Gupta potential, highlighting how different potentials influence predicted structures.
Findings
Marks decahedra dominate at larger sizes
Structures differ significantly from previous glue potential results
Potential choice critically affects cluster structure predictions
Abstract
The lowest-energy structures of lead clusters interacting via a Gupta potential are obtained for N<151. Structures based on Marks decahedra dominate at the larger sizes. These results are very different from those obtained previously using a lead glue potential, and the origins of the differences are related back to differences in the potential.
