The structural and electronic properties of NbSin-/0 (n = 3-12) clusters: anion photoelectron spectroscopy and ab initio calculations.


Niobium-doped silicon clusters, NbSin- (n = 3-12), were generated by laser vaporization and investigated by anion photoelectron spectroscopy. The structures and electronic properties of NbSin- anions and their neutral counterparts were investigated with ab initio calculations and compared with the experimental results. It is found that the Nb atom in NbSin… (More)
