Examination of permittivity for depolarization field of ferroelectric by ab initio calculation, suggesting hidden mechanisms
Abstract 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...
