Abstract
Currently static and dynamic behaviour of ferroelectric materials are
described either numerically using the Landau-Devonshire (LD) model of phase
transitions or various empirical formulae obtained by fitting experimental data of
specific ferroelectric substances such as barium titanate, triglycine sulfate and lead
titanate. As such ferroelectric phenomena such as switching current transients
switching time and polarization relaxation are described by separate empirical
formulae but lack a unified description based upon a common theoretical framework.
