Sánchez-Carrera, Jungwon Park, Hee-Tae Jung*, Matteo Cargnello* INTRODUCTION: Multimetallic nanocrystals exhibit physical and chemical properties unattainable in monometallic systems, arising from the synergistic interplay of their constituent elements. Synthesizing these materials with precise control over their size and composition represents an important goal. Differences in reduction potentials, interfacial energies, and nucleation and growth kinetics among metal precursors create both thermodynamic and kinetic challenges that often lead to asynchronous reduction and incorporation processes. Rather than forming a single, uniform product, these disparities frequently generate multiple particle populations with distinct sizes and compositions. …
