Investigating the Electromechanical Behavior of Unconventionally Ferroelectric -based Capacitors Through Operando Nanobeam X-ray Diffraction
Evgenios Stylianidis, Pranav Surabhi, Ruben Hamming-Green +13
Understanding various aspects of ferroelectricity in hafnia-based nanomaterials is of vital importance for the development of future non-volatile memory and logic devices. Here, th…
Origin of negative electrocaloric effect in Pnma-type antiferroelectric perovskites
Ningbo Fan, Jorge Íñiguez, L. Bellaiche +1
Anomalous electrocaloric effect (ECE) with decreasing temperature upon application of an electric field is known to occur in antiferroelectrics (AFEs), and previous understanding r…
First-principles Landau-like potential for BiFeO and related materials
Natalya S. Fedorova, Dmitri E. Nikonov, Hai Li +2
In this work we introduce the simplest, lowest-order Landau-like potential for BiFeO and La-doped BiFeO as an expansion around the paraelectric cubic phase in powers of pol…
Giant voltage amplification from incipient ferroelectric states
Mónica Graf, Hugo Aramberri, Pavlo Zubko +1
Ferroelectrics subject to suitable electric boundary conditions present a steady negative capacitance response. When the ferroelectric is in a heterostructure, this behavior yields…
