Abstract

Heterostructure nanocrystals (NCs) of γ-Fe₂O₃ and MS (M = Zn, Cd, Hg) are synthesized. The large lattice mismatch between γ-Fe₂O₃ and MS NCs leads to noncentrosymmetric structures. Crystallographic planes at the heterojunctions are identified by high-resolution transmission electron microscopy. Preferential formation of trimers and higher oligomers for ZnS and dimers or isolated particles for CdS and HgS with γ-Fe₂O₃ NCs are observed and explained by changes in the effective mismatch between the coincidence lattices of the most commonly observed junction planes.
