Pyroelectric and electrocaloric properties of core-shell HfxZr1-xO2 nanoparticles: theory and experiment
Anna N. Morozovska, Oleksandr S. Pylypchuk, Nicholas V. Morozovsky +2
Nanosized hafnia-zirconia (HfxZr1-xO2) in the form of thin films, multilayers, and nanoparticles is one of the most promising CMOS-compatible ferroelectric materials for advanced e…
Interfacial Effects and Negative Capacitance State in P(VDF-TrFE) Films with BaTiO3 Nanoparticles
Oleksii V. Bereznykov, Oleksandr S. Pylypchuk, Victor I. Styopkin +7
We analyze the temperature dependences of the effective dielectric permittivity of P(VDF-TrFE) films with BaTiO3 nanoparticles (with the average size 24 nm). Transition from a weak…
Anomalous Behavior of the Dielectric and Pyroelectric Responses of Ferroelectric Fine-Grained Ceramics
Oleksandr S. Pylypchuk, Serhii E. Ivanchenko, Mykola Y. Yelisieiev +12
We revealed the anomalous temperature behavior of the giant dielectric permittivity and unusual frequency dependences of the pyroelectric response of the fine-grained ceramics prep…
