摘要
We report a theoretical investigation of neutral AuxAgyCuz and cationic AuxAgyCuz+ ternary clusters, for x + y+z = 5 and 6. Our study is performed within density functional theory at the TPSSTPSS/SDD level. The geometries, chemical order, binding energy, mixing energy, second difference in the energy, adiabatic ionisation potential of these clusters are evaluated as a function of the whole concentration range. The most probable dissociation channels and the corresponding dissociation energies for the most stable clusters are also determined and discussed. @@@ [GRAPHICS] @@@ .
