A first-principles study of oxygen vacancy pinning of domain walls in PbTiO3
Lixin He, David Vanderbilt
We have investigated the interaction of oxygen vacancies and 180-degree domain walls in tetragonal PbTiO3 using density-functional theory. Our calculations indicate that the vacanc…

Extrinsic models for the dielectric response of CaCu{3}Ti{4}O{12}
Morrel H. Cohen, J. B. Neaton, Lixin He +1
The large, temperature-independent, low-frequency dielectric constant recently observed in single-crystal CaCu{3}Ti{4}O{12} is most plausibly interpreted as arising from spatial in…
