Embedded Ferroelectric Nanoclusters can drive Polarization Reversal in a Non-Ferroelectric Polar Film via the Proximity Effect
Anna N. Morozovska, Eugene A. Eliseev, Sergei V. Kalinin +3
Heterogeneous nucleation from defects dominates the electric field required for polarization switching of ferroelectrics. Here, we consider the switching of a nominally non-switcha…
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…
Sizes of Ferroelectricity Appearance and Disappearence in Nanosized Hafnia-Zirconia:Landau-type Theory
Anna N. Morozovska, Eugene A. Eliseev, Sergei V. Kalinin +1
Nanosized hafnia-zirconia HfxZr1-xO2 in the form of thin films, multilayers and heterostructures are indispensable silicon-compatible ferroelectric materials for advanced electroni…
Tip-Based Proximity Ferroelectric Switching and Piezoelectric Response in Wurtzite Multilayers
Eugene A. Eliseev, Anna N. Morozovska, Sergei V. Kalinin +2
Proximity ferroelectricity is a novel paradigm for inducing ferroelectricity, where a non-ferroelectric polar material, which is unswitchable with an external field below the diele…
Proximity Ferroelectricity in Compositionally Graded Structures
Eugene A. Eliseev, Anna N. Morozovska, Sergei V. Kalinin +2
Proximity ferroelectricity is a novel paradigm for inducing ferroelectricity in a non-ferroelectric polar material such as AlN or ZnO that are typically unswitchable with an extern…
Polarization switching on the open surfaces of the wurtzite ferroelectric nitrides: ferroelectric subsystems and electrochemical reactivity
Yongtao Liu, Anton V. Ievlev, Eugene A. Eliseev +5
Binary ferroelectric nitrides are promising materials for information technologies and power electronics. However, polarization switching in these materials is highly unusual. From…
