METHOD OF CONTROLLING SHAPE OF SYNTHESIZED FERROELECTRIC OXIDE NANOCRYSTAL PARTICLES

摘要

Shape controlled synthesis of ferroelectric nanocrystals such as barium titanate (BaTiO3) nanocrystals is described. By tuning the molar ratio between the surfactant and the metal precursors, BaTiO3 nanocrystals with different shapes are readily obtained. This provides the nanoscopic ferroelectric building blocks for the fabrication of various electronic devices, as well as for fundamental research in nanoscience and nanotechnology.
