Domain Size Dependence of Piezoelectric Properties of Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
The domain size dependence of piezoelectric properties of ferroelectrics is investigated using a continuum Ginzburg-Landau model that incorporates the long-range elastic and electr…
Impedance spectroscopy study on post-annealing-tuned polycrystalline CaCu3Ti4O12 films: Evidence of Barrier Layer Capacitor Effects
Liang Fang, Mingrong Shen, Zhenya Li +1
In this paper, impedance spectroscopy study was performed to establish the electrical property and microstructure relations of the as-deposited and post-annealed polycrystalline CC…
Electromechanical Properties of Multi-Domain Ferroelectrics
Rajeev Ahluwalia, Turab Lookman, Avadh Saxena +1
We study theoretically the influence of the underlying domain microstructure on the electromechanical properties of ferroelectrics. Our calculations are based on a continuum approa…
Effects of post-anneal conditions on the dielectric properties of CaCu3Ti4O12 thin films prepared on Pt/Ti/SiO2/Si substrates
Liang Fang, Mingrong Shen, Wenwu Cao
High-dielectric-constant CaCu3Ti4O12 (CCTO) thin films were prepared on Pt/Ti/SiO2/Si(100) substrates by pulsed-laser deposition. The 480 nm thick polycrystalline films have prefer…
Effect of surface induced nucleation of ferroelastic domains on polarization switching behavior in constrained ferroelectrics
Rajeev Ahluwalia, Wenwu Cao
The role of the surface during polarization switching in constrained ferroelectrics is investigated using the time-dependent Ginzburg-Landau theory. The model incorporates the elas…
