Large-scale synthesis of In₂O₃ nanocubes was realized by modulating experimental parameters including the heating and depositing temperatures through the chemical vapor deposition (CVD) method. The configuration of In₂O₃ nanocubes indicated that the growth was isotropic along three equivalent crystallographic directions [100]. A nondynamic equilibrium growth model was proposed to explain the formation of In₂O₃ nanocubes combined with two contrastive experiments. These two experiments indicated that the formation of nanocubes depended on two crucial factors: relatively low growth temperature and high supersaturation ratio. The dynamic growth process is discussed in depth. The research results may not only facilitate the exploration of new approaches of preparing various nanostructures for potential technical applications but also give a deeper understanding of the fundamental physical and chemical processes of CVD methods.
