Theoretical study of neutral and anionic group III nitride clusters: MnNn (M =Al, Ga, and In; n = 4-6)

The results of a theoretical study of MnNn (M =Al, Ga, and In; n = 4,5,6) neutral and anionic clusters are reported that focus on the changes in structural and electronic properties upon the addition of an electron to the corresponding neutral clusters. The atomic charge analysis showed that the extra electron is localized on the metal atoms, irrespective of the lowest energy structural configurations of these clusters.
