Well‐defined ZnSe nanocrystallites are formed on the van der Waals' surface of a layered semiconductor, GaSe, during deposition at elevated temperatures (see Figure). This growth process—termed van der Waals' condensation—is governed by a quasi‐two‐dimensional nucleation and growth made possible by the extremely weak substrate–cluster interaction.
