A Strain-Driven Morphotropic Phase Boundary in BiFeO ₃ [PDF]

Science, 2009
Biffed into Shape BiFeO 3 is known to have a very large ferroelectric polarization. Although the bulk ground state is rhombohedral (with the electrical polarization along the [111] direction), in thin films and under epitaxial strain, the material can be tetragonally ...

Electrical and Thermal Properties of Na1–xLixNbO3 (x = 0.08, 0.1 and 0.2) Ceramics Near the Morphotropic Phase Boundary Region [PDF]

Archives of Metallurgy and Materials, 2017
Na1-xLixNbO3 ceramics (for x = 0.08, 0.1, 0.2) were fabricated by the conventional solid state reaction method. The influence of LiNbO3 on the microstructure, electric, thermal properties of Na1-xLixNbO3 ceramics was studied and a significant influence ...

Change in the magnetic structure of (Bi,Sm)FeO3 thin films at the morphotropic phase boundary probed by neutron diffraction [PDF]

APL Materials, 2014
We report on the evolution of the magnetic structure of BiFeO3 thin films grown on SrTiO3 substrates as a function of Sm doping. We determined the magnetic structure using neutron diffraction. We found that as Sm increases, the magnetic structure evolves

The monoclinic phase in PZT: New light on morphotropic phase boundaries [PDF]

AIP Conference Proceedings, 2000
A summary of the work recently carried out on the morphotropic phase boundary (MPB) of PZT is presented. By means of x-ray powder diffraction on ceramic samples of excellent quality, the MPB has been successfully characterized by changing temperature in a series of closely spaced compositions.

Crystal structure and piezoelectric properties of 0.79(Na0.5Bi0.5)TiO3-0.05BaTiO3-0.16(K0.5Bi0.5)TiO3 ceramics prepared by solid–state method [PDF]

Heliyon
The solid-state reaction technique was employed to synthesize lead-free ceramics, specifically (1-x-y)(Na0.5Bi0.5)TiO3-xBaTiO3-y(K0.5Bi0.5)TiO3. For attaining a pure perovskite phase, it was found that the optimal calcination temperature is 1000 °C ...

A structural study of BiFeO3 - PbTiO3 thin films deposited by pulsed laser deposition [PDF]

, 2011
In recent years ferroelectric thin films have received an enormous amount of attention due to their potential use in electronic device applications. Bismuth ferrite lead titanate (xBiFeO3 â (1-x)PbTiO3) thin films are of special interest due to their ...

A CMOS-compatible morphotropic phase boundary [PDF]

Nanotechnology, 2021
Abstract Morphotropic phase boundaries (MPBs) show substantial piezoelectric and dielectric responses, which have practical applications. The predicted existence of MPB in HfO 2 –ZrO 2 solid solution thin film has provided a new way to

Laser-Induced Phase Control of Morphotropic Phase Boundary Hafnium-Zirconium Oxide. [PDF]

ACS Appl Mater Interfaces
A novel approach to delicately control the phase of a ferroelectric has been developed using a continuous-wave laser scanning annealing (CW-LSA) process. After proper process optimization, the equivalent oxide thickness (EOT) of 3.5 Å with a dielectric constant (κ) of 68 Å is achieved from HZO in a metal-ferroelectric-metal (MFM) capacitor structure ...

Noncollinear ferrielectricity and morphotropic phase boundary in monolayer GeS [PDF]

Physical Review B, 2021
Two-dimensional polarity is intriguing but remains in the early stage. Here a structural evolution diagram is established for monolayer GeS, which leads to a noncollinear ferrielectric $\ensuremath{\delta}$ phase energetically as stable as the ferroelectric $\ensuremath{\alpha}$ phase.
