چکیده

The electronic structure of small fullerenes determined experimentally by anion photoelectron spectroscopy is compared with calculations. A huge mass signal and a large gap of 1.3 eV comparable to the gap of C70 have been found for C32, indicating that this cluster is the most stable fullerene below C60. Also C36, C44, and C50 exhibit large gaps and surprisingly high stabilities. The criteria for the selection of clusters sufficientl stable to form a cluster material are discussed.

Spontaneous formation and stability of small GaP fullerenes

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, clos...
