Phys. Rev. B 61, 2329–2334 (2000)Structures and dynamical properties of Cn, Sin, Gen, and Snn clusters with n up to 13Received 12 July 1999; published in the issue dated 15 January 2000 Car-Parrinello molecular dynamics simulated annealings were carried out for clusters Sin, Gen, and Snn (n<~13). We investigate the temperature regions in which these clusters transform from a “liquidlike” phase to a “solidlike” phase, and then from the “solidlike” phase to the ground-state structures. Additional simulated annealing was also performed for the cluster C13 which is selected as a prototype of small carbon clusters. In addition to the discovery of structures for Sn and Ge clusters, our simulation results also provide insights into the dynamics of cluster formation. © 2000 The American Physical Society URL:
