90-degree Ferroelectric Domains in PbTiO3: Experimental Observation and Molecular Dynamics Simulations

Kenta Aoyagi, Takeshi Nishimatsu, Takanori Kiguchi +5

We report observation of 90-degree ferroelectric domain structures in transmission electron microscopy (TEM) of epitaxially-grown films of PbTiO3. Using molecular dynamics (MD) sim…
