Examination of permittivity for depolarization field of ferroelectric by ab initio calculation, suggesting hidden mechanisms
Electrostatics of depolarization field E(d) in relation to the polarization is studied. In particular, the value of permittivity for E(d) (ε(d)) in prototypical situations of ferroelectrics, including Mehta formula, is examined by ab initio calculations. By using spontaneous polarization P(S) corres...
