Exploring Nanoscale Ferroelectricity in Doped Hafnium Oxide by Interferometric Piezoresponse Force Microscopy
Liam Collins, Umberto Celano
Hafnium oxide (HfO2)-based ferroelectrics offer remarkable promise for memory and logic devices in view of their compatibility with traditional silicon CMOS technology, high switch…
Fast Scanning Probe Microscopy via Machine Learning: Non-rectangular scans with compressed sensing and Gaussian process optimization
Kyle P. Kelley, Maxim Ziatdinov, Liam Collins +5
Fast scanning probe microscopy enabled via machine learning allows for a broad range of nanoscale, temporally resolved physics to be uncovered. However, such examples for functiona…
Super-resolution and signal separation in contact Kelvin probe force microscopy of electrochemically active ferroelectric materials
Maxim Ziatdinov, Dohyung Kim, Sabine Neumayer +7
Imaging mechanisms in contact Kelvin Probe Force Microscopy (cKPFM) are explored via information theory-based methods. Gaussian Processes are used to achieve super-resolution in th…
Piezoresponse phase as variable in electromechanical characterization
Sabine M. Neumayer, Sahar Saremi, Lane W. Martin +5
Piezoresponse force microscopy (PFM) is a powerful characterization technique to readily image and manipulate ferroelectrics domains. PFM gives insight into the strength of local p…
Imaging Mechanism for Hyperspectral Scanning Probe Microscopy via Gaussian Process Modelling
Maxim Ziatdinov, Dohyung Kim, Sabine Neumayer +5
We investigate the ability to reconstruct and derive spatial structure from sparsely sampled 3D piezoresponse force microcopy data, captured using the band-excitation (BE) techniqu…
Self-Assembled Room Temperature Multiferroic BiFeO3-LiFe5O8 Nanocomposites
Yogesh Sharma, Radhe Agarwal, Liam Collins +11
Multiferroic materials have driven significant research interest due to their promising technological potential. Developing new room-temperature multiferroics and understanding the…
