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…
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…
