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…

Role of Oxygen Vacancies in Stabilizing the Orthorhombic Phases of Hf0.5Zr0.5O2 Nanoparticles
Yuriy O. Zagorodniy, Eugene A. Eliseev, Valentin V. Laguta +13
In this work we study the stabilization of the orthorhombic phases in small Hf0.5Zr0.5O2 nanoparticles (average size ~ 7 nm) annealed under different oxygen partial pressures. Conc…

Stress-Induced Ferroelectricity in Hafnium Oxide Core-Shell Nanoparticles
Anna N. Morozovska, Eugene A. Eliseev, Richard +3
In contrast to hafnia (HfO2) thin films, where the appearance of switchable ferroelectric polarization can be induced by strain or defect engineering, reliable methods for controll…
