Energy storage properties of ferroelectric nanocomposites
Zhijun Jiang, Zhenlong Zhang, Sergei Prokhorenko +3
An atomistic effective Hamiltonian technique is used to investigate the finite-temperature energy storage properties of a ferroelectric nanocomposite consisting of an array of BaTi…
Revealing the Three-Dimensional Arrangement of Polar Topology in Nanoparticles
Chaehwa Jeong, Juhyeok Lee, Hyesung Jo +8
In the early 2000s, low dimensional systems were predicted to have topologically nontrivial polar structures, such as vortices or skyrmions, depending on mechanical or electrical b…
Microscopic Origin of the Electric Dzyaloshinskii-Moriya Interaction
Peng Chen, Hong Jian Zhao, Sergey Prosandeev +2
The microscopic origin of the electric Dzyaloshinskii-Moriya interaction (eDMI) is unveiled and discussed by analytical analysis and first-principles based calculations. As similar…
A new look at the temperature-dependent properties of the antiferroelectric model PbZrO3: an effective Hamiltonian study
Kinnary Patel, Bin Xu, Sergey Prosandeev +4
A novel atomistic effective Hamiltonian scheme, incorporating an original and simple bilinear energetic coupling, is developed and used to investigate the temperature dependent phy…
Energy storage in lead-free Ba(Zr, Ti)O relaxor ferroelectrics: Large densities and efficiencies and their origins
Zhijun Jiang, Sergey Prosandee, L. Bellaiche
An atomistic first-principles-based effective Hamiltonian is used to investigate energy storage in Ba(ZrTi)O relaxor ferroelectrics, both in their bulk and ep…
Electrocaloric effects in multiferroics
Zhijun Jiang, Bin Xu, Sergey Prosandeev +4
An atomistic effective Hamiltonian is used to compute electrocaloric (EC) effects in rare-earth substituted BiFeO multiferroics. A phenomenological model is then developed to…
