Morphotropic Phase Boundary Engineering via Heterostructure for Low‐Voltage Ferroelectric Capacitors

Advanced Electronic Materials
We investigated morphotropic phase boundary (MPB) engineering via heterostructure design to achieve low‐voltage and fast‐switching ferroelectric capacitors based on HfxZr1‐xO2 (HZO). By integrating an MPB layer with a conventional ferroelectric HZO layer

Local-scale structures across the morphotropic phase boundary in PbZr1−xTixO3 [PDF]

IUCrJ, 2018
Lead zirconate titanate (PZT) is one of the most widely studied piezoelectric materials, mainly because of its `mysterious' relationship between the so-called morphotropic phase boundary (MPB) and its strong piezoelectric coupling factor.

Large Electrocaloric Effect in Stretched Relaxor Ferroelectric Polymers near Morphotropic Phase Boundary

Chemistry
Use of the morphotropic phase boundary (MPB) is a promising approach to enhance the electrocaloric effect in ferroelectric polymers. This is usually achieved by a composition method, and polymer processing near the MPB to tune electrocaloric response has

Phase transitions in the ferroelectric relaxor (1−x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 close to the morphotropic phase boundary [PDF]

, 2022
Structural transformations of unpoled (1−x)Pb(Mg1/3Nb2/3)O3−xPbTiO3(PMN-PT) single crystals (x=0.28 and x=0.32) were analyzed by calorimetry and acoustic spectroscopy. The compositions are close to the morphotropic boundary (MPB).
