Disordered ferroelectricity in the PbTiO3/SrTiO3 superlattice thin film
APL Materials, 2017 The PbTiO3/SrTiO3 superlattice thin films with a low volume fraction of PbTiO3 have not attracted much interest because they are thought to exhibit only a paraelectric state.

Nanoscale domain engineering in SrRuO3 thin films
APL Materials, 2023 We investigate nanoscale domain engineering via epitaxial coupling in a set of SrRuO3/PbTiO3/SrRuO3 heterostructures epitaxially grown on (110)o-oriented DyScO3 substrates.

Soft Mode in cubic PbTiO3 by Hyper-Raman Scattering [PDF]
, 2012 Hyper-Raman scattering experiments allowed collecting the spectra of the lowest F1u-symmetry mode of PbTiO3 crystal in the paraelectric phase up to 930K as well as down to about 1K above the phase transition.

Enhancing polarization by electrode-controlled strain relaxation in PbTiO3 heterostructures
APL Materials, 2016 A large remanent polarization close to theoretical value 80 μC/cm2 of bulk PbTiO3 is achieved in epitaxial heterostructures of (120–600)-nm-thick PbTiO3 films grown by pulsed laser deposition on (001) SrTiO3 substrate using a 100-nm-thick SrRuO3 bottom ...

Unusual behaviour of the ferroelectric polarization in PbTiO$_{3}$/SrTiO$_{3}$ superlattices [PDF]
, 2005 Artificial PbTiO$_{3}$/SrTiO$_{3}$ superlattices were constructed using off-axis RF magnetron sputtering. X-ray diffraction and piezoelectric atomic force microscopy were used to study the evolution of the ferroelectric polarization as the ratio of PbTiO$

Efficacy of the DFT+U formalism for modeling hole polarons in perovskite oxides
, 2014 We investigate the formation of self-trapped holes (STH) in three prototypical perovskites (SrTiO3, BaTiO3, PbTiO3) using a combination of density functional theory (DFT) calculations with local potentials and hybrid functionals.

Ferroelectricity in ultra-thin perovskite films
, 2005 We report studies of ferroelectricity in ultra-thin perovskite films with realistic electrodes. The results reveal stable ferroelectric states in thin films less than 10 \AA thick with polarization normal to the surface.

, 2009 A first principles embedded cluster approach is used to calculate O chemical shielding tensors, sigma, in prototypical transition metal oxide ABO_3 perovskite crystals. Our principal findings are 1) a large anisotropy of sigma between deshielded sigma_x ~

Ferroelectric domain walls in PbTiO3 are effective regulators of heat flow at room temperature.
Nano letters (Print), 2019 Achieving efficient spatial modulation of phonon transmission is an essential step on the path to phononic circuits using "phonon currents." With their intrinsic and reconfigurable interfaces-domain walls (DWs)-ferroelectrics are alluring candidates to ...
