Structural evidence for ultrafast polarization rotation in ferroelectric/dielectric superlattice nanodomains
Hyeon Jun Lee, Youngjun Ahn, Samuel D. Marks +16
Weakly coupled ferroelectric/dielectric superlattice thin film heterostructures exhibit complex nanoscale polarization configurations that arise from a balance of competing electro…
Controlling ferroelectric hysteresis offsets in PbTiO based superlattices
Simon Divilov, Hsiang-Chun Hsing, Mohammed Humed Yusuf +9
Ferroelectric materials are characterized by degenerate ground states with multiple polarization directions. In a ferroelectric capacitor this should manifest as equally favourable…
Role of temperature-dependent electron trapping dynamics in the optically driven nanodomain transformation in a PbTiO/SrTiO superlattice
Joonkyu Park, Youngjun Ahn, Jack A. Tilka +6
The spontaneously formed striped polarization nanodomain configuration of a PbTiO/SrTiO superlattice transforms to a uniform polarization state under above-bandgap illu…
