文摘
- •
Reaction temperature and KOH concentration are the keys to grow BiFeO3 crystal phase.
- •
Growth mechanism of BiFeO3 is closely related to Bi:Fe molar ratio in solution.
- •
Large BiFeO3 crystal was grown at high KOH concentration and low supersaturation.
- •
Increasing compactedness will reduce surface defect and improve crystal quality.
