Abstract
The capacitance of PbZrO3–Pb(Zr0.8Ti0.2)O3 epitaxial multilayers is significantly enhanced as the number of interfaces increases at the same total thickness of the structure. A possible explanation for this enhancement can be the increase of the dielectric susceptibility due to the presence of some interfacial polarization related, for instance, to trapped charges at the multilayer interfaces. The presented results suggest that capacitance tuning is achievable in antiferroelectric–ferroelectric epitaxial multilayers.
