Abstract: The geometric configurations and electronic structures of AlnO2± (n=1-10) clusters were studied using the B3LYP density functional theory (DFT) at the 6-311G** level. The ground state structure, vibrational frequency, charge transfer, and molecular orbital of the doped clusters are discussed. The results showed that the ground states of the AlnO2± (n>1) clusters were combinations of two smaller AlmO (mn) fragments and the Al clusters shared an Al atom or local structure of one Al4O2. Stability information for the AlnO2± clusters was obtained by analyzing the energy of the ground state structure.

Key words: AlnO2± cluster, Ground state structure, Density functional theory, Stability
