Fig. 1: Capacitance enhancement induced by the static NC effect at room temperature.

a XRD data of the PZO film with the orthorhombic phase deposited on the LSMO bottom electrode with STO substrate. The peaks marked by green triangles represent the STO phase and the peaks marked by black dots represent the LSMO phase. The red stars represent the (00l) orientation in pseudocubic index of the PZO films. b Antiferroelectric polarization P as a function of the electric field E (P–E). c Small signal capacitance–voltage (C–V) characteristics measured at 100 kHz for the Pt/PZO/LSMO capacitor and Pt/a-PZO/LSMO capacitor. d Comparison of C–V characteristics of Pt/a-HfO2/PZO/LSMO, Pt/a-HfO2/a-PZO/LSMO, and Pt/a-HfO2/LSMO capacitors.
