This research aims to understand how scan path and initial state affect polarization switching in PZT thin films.
Used automated AFM-based writing for domain manipulation
Employed quantitative 3D piezoresponse force microscopy
Conducted phase-field modeling to assess domain configurations.
Box-in-box raster scans stabilize ordered stripe superdomains, leading to fewer variants
Spiral trajectories result in frustrated mixed-variant states with diverse microstructures
Local configuration at nucleation sites notably impacts final morphology.
