Absence of lateral domain wall mobility in Zn1-xMgxO thin films
Jack Eckstein, Kyle P. Kelley, William Prudnick +4
Polarization reversal in ferroelectrics arises from the coupled processes of domain nucleation and subsequent growth, yet the governing mechanisms differ fundamentally between clas…
Electromechanical Hysteresis in Phase Change Material Sb2S3
Jack Kaman, Evan Musterman, Kyle P. Kelley +3
Antimony sulfide is an emerging phase change material for optical and electrical memory and computation elements. It has additionally been reported as a ferroelectric, with recent…
Autonomous scanning probe microscopy with hypothesis learning: Exploring the physics of domain switching in ferroelectric materials
Yongtao Liu, Anna Morozovska, Eugene Eliseev +4
We report the development and implementation of a hypothesis learning based automated experiment, in which the microscope operating in the autonomous mode identifies the physical l…
Reversible long-range domain wall motion in an improper ferroelectric
M. Zahn, A. M. Müller, K. P. Kelley +8
Reversible ferroelectric domain wall movements beyond the 10 nm range associated with Rayleigh behavior are usually restricted to specific defect-engineered systems. Here, we demon…
Photoinduced Patterning of Oxygen Vacancies to Promote the Ferroelectric Phase of
Thomas E Beechem, Fernando Vega, Samantha T. Jaszewski +3
Photoinduced reductions in the oxygen vacancy concentration were leveraged to increase the ferroelectric phase fraction of (HZO) thin-films. Modest (…
