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…
Phase evolution and thermal stability of high Curie temperature BiScO-PbTiO-Pb(CdNb)O ceramics near MPB
Zhencheng Lan, Kaiyuan Chen, Xiafeng He +8
Piezoelectric and ferroelectric ceramics with a high Curie temperature (Tc) have attracted a growing attention owning to their applications under severe environments. In this work,…
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…
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…
