Method to Achieve the Morphotropic Phase Boundary in HfxZr1-xO2 by Electric Field Cycling for DRAM Cell Capacitor Applications

, 2021
We demonstrate a novel method using electric field cycling to induce a phase transition in HfxZr1-xO2 to reach the morphotropic phase boundary of tetragonal and orthorhombic phase.

Structure and Physical Properties of PZT-PMnN-PSN Ceramics Near the Morphological Phase Boundary

Advances in Materials Science and Engineering, 2014
The 0.9Pb(ZrxTi1−x)O3-0.07Pb(Mn1/3Nb2/3)O3-0.03Pb(Sb1/2Nb1/2)O3 (PZT-PMnN-PSN) ceramics were prepared by columbite method. The phase structure of the ceramic samples was analyzed.

Strain-gradient mediated local conduction in strained bismuth ferrite films

Nature Communications, 2019
In semiconductors strain gradients can separate light induced electron-hole pairs via the flexo-photovoltaic effect. Here the authors show that this effect can also account for the enhancement of the photoconduction in certain phase regions at the ...

Evolution of local heterogeneity towards flat free energy landscape: Optimization of piezoelectric response in PNN-PZ-PT at morphotropic phase boundary

Chemical Physics Impact
A precisely specified compositional landscape of two distinct ferroelectric systems – morphotropic phase boundary (MPB) – possesses ultrahigh piezoelectricity, where generically a flat energy profile is favoured under thermodynamic consideration.

Phase coexistence near a morphotropic phase boundary in Sm-doped BiFeO3 films [PDF]

Applied Physics Letters, 2010
We have investigated heteroepitaxial films of Sm-doped BiFeO3 with a Sm-concentration near a morphotropic phase boundary. Our high-resolution synchrotron x-ray diffraction, carried out in a temperature range of 25 to 700 °C, reveals substantial phase coexistence as one changes temperature to crossover from a low-temperature PbZrO3-like phase to a high ...

Thin Film Near Morphotropic Phase Boundary

, 2021
Recently, based on the phase-field modeling, it is predicted that Hf1-xZrxO2 (HZO) exhibits the morphotropic phase boundary (MPB) in its compositional phase diagram.
