AB - Clarifying the phase distribution of liquid metallic alloys is of both scientific and technological importance. In the macroscopic scale, the Gibbs prediction is experimentally discovered to be only partially valid. By using molecular dynamics simulations, we verify that different phase segregation patterns similarly exist in bimetallic nanodroplets. In the Au–Pt system, phase segregation is confined to a single surface layer, which is independent of composition ratios. In contrast, core–shell separation and uniform distribution are discovered in the nanodroplets with other components. This diversity originates from the tendency to minimize the free energy, which hinges on the competition between potential energy and the entropy term. The relevant results could provide a perspective toward the design of functional metallic nanodroplets.Graphical Abstract[graphic not available: see fulltext]
