Ferroelectric polarization switching with a remarkably high activation-energy in orthorhombic GaFeO3 thin films
Seungwoo Song, Hyun Myung Jang, Nam-Suk Lee +5
Orthorhombic GaFeO3 (o-GFO) with the polar Pna21 space group is a prominent ferrite by virtue of its piezoelectricity and ferrimagnetism, coupled with magneto-electric effects. Her…
Nonpolar resistive memory switching with all four possible resistive switching modes in amorphous ternary rare earth LaHoO3 thin films
Yogesh Sharma, Shojan Pavunny, Esteban Fachini +2
We studied the resistive memory switching in pulsed laser deposited amorphous LaHoO3 (LHO) thin films for non-volatile resistive random access memory (RRAM) applications. Nonpolar…
Electron-Beam Driven Relaxation Oscillations in Ferroelectric Nanodisks
Nathaniel Ng, Rajeev Ahluwalia, Ashok Kumar +3
Using a combination of computational simulations, atomic-scale resolution imaging and phenomenological modelling, we examine the underlying mechanism for nanodomain restructuring i…
