| Summary: | 碩士 === 國立清華大學 === 物理系 === 103 === Ferroelectric materials have aroused considerable research interest for their important applications in memory devices due to hysteresis effects. In the present
work, we seek a simple method to prepare ferroelectric materials at low cost while maintaining their basic ferroelectric hysteresis effect. We anticipate that the pulsed laser deposition process may be replaced by our improved preparation method in the future. The BiFeO3 particles were synthesized by a hydrothermal method, then
composited with PVDF. An external electric field was then applied to correct the direction of total dipole moment of the particles in the sample preparation process
for enhancing the polarization.
