Abstract:

We report the spontaneous formation of a GaP fullerene cage in ab initio molecular dynamics simulations starting from a bulk fragment. A systematic study of the geometric and electronic properties of neutral and ionized GaP clusters suggests the stability of heterofullerenes formed by a compound with zinc blende bulk structure. We find that GaP fullerenes up to 28 atoms have high symmetry, closed electronic shells, large highest occupied molecular orbital-lowest unoccupied molecular orbital energy gaps, and do not dissociate when ionized. We compare our results for GaP with those obtained by other groups for the corresponding BN clusters.
