Abstract Scope |
Ferroelectrics have high application potential in various fields within the allowance of their high electrical property when the composition of phases is closed to the morphotropic phase boundary (MPB) region. MPB is expressed as a boundary of two distinct ferroelectric phases. Traditionally, due to the solubility limitations of them, densification via sintering process have been chosen to adjust the composition of the MPB in ferroelectric ceramics. However, the sintering process often accompany the grain growth or secondary phases formation. As a solution to form the MPB without the limitations, nano-clustering of ferroelectrics via aerosol deposition can artificially implement the MPB in the nano-clustered thick films with strong bonding at the interfaces between the grains of the different phases. This study demonstrates that the nano-clustered films comprising PZ and PT presented enhanced electrical properties at the MPB composition like the MPB properties observed in single-phase PZT films. |
