Abstract :
The dynamics of domains stability of a 120-nm-thick Z-cut single-crystal LiTaO3 thin film obtained through the Smart Cut™ technology is investigated using Piezoresponse Force Microscopy. The artificially created -Z domains were found to completely relax, driven by the large built-in field observed in the structure. A constant domain wall velocity of 0.2-0.6 nm/s was extracted from the evolution of the equivalent radius of the different domains observed.
