Abstract

Ab initio Langevin molecular dynamics simulations were performed to study the structural transformation of tin clusters Sn x (x=6, 7, 10, and 13) at high temperatures. The melting temperatures of these clusters were estimated to be 1300 K, 2100 K, 2000 K, and 1900 K, respectively, which are all above the melting temperature (505 K) of bulk tin. These results are consistent with recent ion mobility measurements.
