Abstract
We report DFT calculations about the global minimum structures, stability and electronic properties of small free Ni x Sn y nanoalloys (x + y ≤ 5), by using the free SIESTA code. Our results show that the optimized structures of these binary nanoalloys prefer geometries with high coordination and show significant variations as compared to lower energies structures of the pure clusters. The excess energy reveals a favorable mixing of the constituent atoms for all the clusters studied here. The electronic behavior is analyzed through the ionization potential, electron affinity and hardness.
