 The study of ferroelectric domain switching in C-access-oriented epitaxial PB, ZR-ERS-RUVBINU NOHUB is $0.2T, ERS-RUVBINU NOHUB is $0.8. O underscore three thin films using bias-scanning probe microscopy tips revealed an additional linear dependence on relative humidity in the 28-65% range and identified a growth-limited regime for very short pulses and a nucleation-limited regime for very low tip bias. The study also found a surprisingly long relaxation time on the order of 100 Milizakons, which was related to ionic redistribution both on the surface and within the thin film itself.
