Theory of hypothetical ferroelectric superlattices incorporating head-to-head and tail-to-tail 180 domain walls
Xifan Wu, David Vanderbilt
While electrical compatibility constraints normally prevent head-to-head (HH) and tail-to-tail (TT) domain walls from forming in ferroelectric materials, we propose that such domai…

Systematic treatment of displacements, strains and electric fields in density-functional perturbation theory
Xifan Wu, David Vanderbilt, D. R. Hamann
The methods of density-functional perturbation theory may be used to calculate various physical response properties of insulating crystals including elastic, dielectric, Born charg…
