Journal ArticleDOI
Unusual phase transitions in ferroelectric nanodisks and nanorods
TL;DR: This work performs ab initio studies of ferroelectric nanoscale disks and rods of technologically important Pb(Zr,Ti)O3 solid solutions, and demonstrates the existence of previously unknown phase transitions in zero-dimensional ferroElectric nanoparticles.
Journal ArticleDOI
Virtual crystal approximation revisited: Application to dielectric and piezoelectric properties of perovskites
TL;DR: In this article, the virtual crystal approximation (VCA) was used to predict dielectric and piezoelectric properties of the perovskite solid solution in its paraelectric or ferroelectric phases.
Journal ArticleDOI
Finite-Temperature Properties of Pb\(Zr 1-x Ti x \)O 3 Alloys from First Principles
TL;DR: A low-temperature monoclinic phase is confirmed to exist, and is demonstrated to act as a bridge between the well-known tetragonal and rhombohedral phases delimiting the morphotropic phase boundary (MPB).
Journal ArticleDOI
Giant piezoelectricity of Sm-doped Pb(Mg1/3Nb2/3)O3-PbTiO3 single crystals.

TL;DR: Rare-earth doping is identified as a general strategy for introducing local structural heterogeneity in order to enhance the piezoelectricity of relaxor ferroelectric crystals.
Journal ArticleDOI
Learning through ferroelectric domain dynamics in solid-state synapses.

TL;DR: This work reports on synapses based on ferroelectric tunnel junctions and shows that STDP can be harnessed from inhomogeneous polarization switching and demonstrates that conductance variations can be modelled by the nucleation-dominated reversal of domains.
