Stable structures for Ge-10 cluster and comparative study with Si-10 cluster

Full-potential linear-muffin-tin-orbital molecular-dynamics (FP-LMTO MD) ca lculations have been performed to investigate the structures and energies o f small cluster Ge-10. We get twenty three stable structures for Ge-10. The results suggest that only five structures are stable among the six structu res proposed before, the remainder undergoes a distortion to another more s table form. Making comparison with the structures of Si-10 cluster, we find that there are: much in common between them. But their ground state struct ures are different.
