Enhancing ferroelectric stability: wide-range of adaptive control in epitaxial HfO2/ZrO2 superlattices

Epitaxial growth and structural characterizations of superlattices

(HfO₂)_n/(ZrO₂)_n (n = 2, 3, 6, 11, and 16 unit cells) superlattices were epitaxially grown on (001)-oriented La_0.67Sr_0.33MnO₃ (LSMO)-buffered SrTiO₃ (STO) substrates at 600 °C…
