A general gas‐phase synthesis approach is developed to fabricate heterostructured nanoparticles with well‐defined surfaces and interfaces. The figure shows examples of various nanoparticle morphologies that can be obtained by tuning the phase separation and segregation processes, thereby leading to directional diffusion and well‐defined interfaces at the single‐particle level.
