Strain-induced bent domains in ferroelectric nitrides
Zhijun Jiang, Zhenlong Zhang, Charles Paillard +2
Ferroelectric nitrides have emerged as promising semiconductor materials for modern electronics. However, their domain structures and associated properties are basically unknown, d…
Electro-optic properties from ab initio calculations in two-dimensional materials
Zhijun Jiang, Hongjun Xiang, Laurent Bellaiche +1
Electro-optic (EO) effects relate the change of optical constants by low-frequency electric fields. Thanks to the advent of Density Functional Perturbation Theory (DFPT), the EO pr…

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…
Ultrahigh energy storage density in epitaxial AlN/ScN superlattices
Zhijun Jiang, Bin Xu, Hongjun Xiang +1
Dielectric and antiferroelectric materials are particularly promising for high-power energy-storage applications. However, relatively low energy density greatly hinders their usage…
Linear versus nonlinear electro-optic effects in materials
Zhijun Jiang, Charles Paillard, Hongjun Xiang +1
Two schemes are proposed to compute the nonlinear electro-optic (EO) tensor for the first time. In the first scheme, we compute the linear EO tensor of the structure under a finite…
