In this work, surface segregation phenomena of Au–Pd–Pt trimetallic clusters are investigated by using semi-grand Monte Carlo simulations based on the Gupta potential. It is found that Au atoms are systematically segregated on the surface of the Au–Pd–Pt clusters (6–24at.% higher than the overall Au concentration), due to the competition among the surface energies of Au, Pd, and Pt. The melting properties...
