Probing ferroelectric domain dynamics in free-standing PbTiO3/SrTiO3 superlattices

We propose to perform SXDM on free-standing PbTiO3/SrTiO3 superlattices as a function of applied temperature and field. In these systems, complex hierarchical ferroelectric/ferroelastic superdomain arrangements form. These are expected to be readily reconfigurable under external stimuli, a characteristic that combined with recently discovered domain wall functionalities makes such heterostructures excellent candidates for reconfigurable nanoelectronics. We thus aim to observe such domain dynamics using SXDM in-situ on ID01.
