Abstract
The stability and structures of Titanium-doped Gold clusters AunTi (n=2-16) are studied under the relativistic all-electron density-functional calculations. It is found that the most stable structures of AunTi clusters with n=2-7 are planar. A structural transition of AunTi clusters from two-dimensional to three-dimensional geometry occurs at n=8, while the AunTi (n=12-16) prefer gold cage structure with Ti atom locating at the center. The size-dependence of cluster properties such as binding energy, energy gaps, ionization potentials, and electron affinities have been calculated and analyzed. The Au14Ti cluster is found to have special stability, which may be due to the electron shell effects. Further calculations are performed to study cluster-cluster interaction between two Au14Ti clusters.
