Atom Probe Tomography as an Emerging Tool for Understanding Defect-driven Mechanisms in HfO-based Ferroelectrics
Kasper A. Hunnestad, Catherine Dubourdieu, Alexei Gruverman +1
HfO-based ferroelectrics are essential for the next generation of CMOS-compatible memory and logic devices, yet their performance is governed by a complex interplay between o…
Beyond Scalar Objectives: Expert-Feedback-Driven Autonomous Experimentation for Scientific Discovery at the Nanoscale
Ralph Bulanadi, Jefferey Baxter, Arpan Biswas +5
Self-driving laboratories or autonomous experimentation are emerging as transformative platforms for accelerating scientific discovery. Bayesian optimization (BO) is among the most…
AFM-based Functional Tomography-To Mill or not to Mill, that is the Question!
Niyorjyoti Sharma, Kristina M. Holsgrove, James Dalzell +8
The electrical response of ferroelectric domain walls is often influenced by their geometry underneath the sample surface. Tomographic imaging in these material systems has therefo…
Observation of Antiferroelectric Domain Walls in a Uniaxial Hyperferroelectric
Michele Conroy, Didrik René Småbråten, Colin Ophus +11
Ferroelectric domain walls are a rich source of emergent electronic properties and unusual polar order. Recent studies showed that the configuration of ferroelectric walls can go w…
