Phonon drag thermal Hall effect in metallic strontium titanate. [PDF]

Proc Natl Acad Sci U S A, 2022
Significance We find that the amplitude of the thermal Hall effect (THE) in strontium titanate drastically varies with atomic substitution. It is suppressed when Sr is substituted by Ca, pointing to the role of ferroelectric fluctuations in generating ...

Dual response of osteoblast activity and antibacterial properties of polarized strontium substituted hydroxyapatite—Barium strontium titanate composites with controlled strontium substitution

Journal of Biomedical Materials Research - Part A, 2021
To mimic the electrical properties of natural bone, controlled strontium substitution of both hydroxyapatite and ferroelectric barium titanate were achieved by mixing in the ratio 30:70 by weight.

Heat-to-Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors. [PDF]

Adv Sci (Weinh)
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Response Properties of Electrorheological Composite Hydrophilic Elastomers Based on Different Morphologies of Magnesium-Doped Strontium Titanate [PDF]

Molecules
As smart materials, electrorheological elastomers (EREs) formed by pre-treating active electrorheological particles are attracting more and more attention. In this work, four Mg-doped strontium titanate (Mg-STO) particles with spherical, dendritic, flake-

Heavy Nondegenerate Electrons in Doped Strontium Titanate [PDF]

Physical Review X, 2020
Room-temperature metallicity of lightly doped SrTiO_{3} is puzzling, because the combination of mobility and the effective mass would imply a mean-free path below the Mott-Ioffe-Regel limit and a scattering time shorter than the Planckian time (τ_{P}=ℏ ...

Enhanced superconductivity close to a non-magnetic quantum critical point in electron-doped strontium titanate. [PDF]

Nat Commun, 2019
Studies on quantum critical points (QCP) have focused on magnetic QCPs to date. Remarkable phenomena such as superconductivity due to avoided criticality have been discovered, but we focus here on the non-magnetic counterpart, i.e., the superconductivity

Quantum paraelectricity and structural phase transitions in strontium titanate beyond density functional theory [PDF]

PHYSICAL REVIEW MATERIALS, 2022
We demonstrate an approach for calculating temperature-dependent quantum and anharmonic effects with beyond density-functional theory accuracy. By combining machine-learned potentials and the stochastic self-consistent harmonic approximation, we ...
