Competing phases and domain structures of ferroelectric perovskites: the benefit of epitaxial (110) growth
Lan-Tien Hsu, Takeshi Nishimatsu, Anna Grünebohm
Strain and domain engineering offer powerful routes to control phase and domain stability in ferroelectric thin films. While most studies have focused on (100)-oriented growth, the…

Electric field direction dependence of the electrocaloric effect in BaTiO3
Lan-Tien Hsu, Frank Wendler, Anna Grünebohm
Single-crystalline ferroelectric (FE) perovskites show a large electrocaloric effect at electric field-induced phase transitions, promising for solid-state cooling technologies. Ho…
