Charge effects in donor doped perovskite ferroelectrics
J. Liu, L. Liu, J. Zhang +5
Doping is a widely used method to tune physical properties of ferroelectric perovskites. Since doping can induce charges due to the substitution of certain elements, charge effects…
ATiO/TiO (A=Pb, Sn) superlattice: bridging ferroelectricity and conductivity
S. Raza, R. Zhang, N. Zhang +5
We propose to insert TiO layers to perovskite ATiO to form a superlattice and use first-principles calculations to investigate its basic properties. Our computational analysi…
Origin of sawtooth domain walls in ferroelectrics
J. Zhang, Y. -J. Wang, J. Liu +6
Domains and domain walls are among the key factors that determine the performance of ferroelectric materials. In recent years, a unique type of domain walls, i.e., the sawtooth-sha…
Ewald summation for ferroelectric perovskites with charges and dipoles
D. Wang, J. Liu, J. Zhang +3
Ewald summation is an important technique used to deal with long-range Coulomb interaction. While it is widely used in simulations of molecules and solid state materials, many impo…
Understanding doped perovskite ferroelectrics with defective dipole model
J. Liu, L. Jin, Z. Jiang +6
While doping is widely used for tuning physical properties of perovskites in experiments, it remains a challenge to exactly know how doping achieves the desired effects. Here, we p…
Realization of Quantum Spin Hall State in Monolayer 1T'-WTe2
Shujie Tang, Chaofan Zhang, Dillon Wong +23
A quantum spin Hall (QSH) insulator is a novel two-dimensional quantum state of matter that features quantized Hall conductance in the absence of magnetic field, resulting from top…
