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…
