Growth redox conditions and interface effects govern polarization switching speed, retention and reliability in epitaxial Hf<sub>0.5</sub>Zr<sub>0.5</sub>O<sub>2</sub> thin films

Figure 2. (A-C) Polarization-electric field (P-E) hysteresis loops measured using the PUND method for the three series of samples: (A) STO(001) O2, (B) STO(110) O2, and (C) STO(110) O2/Ar. (D) Thickness dependence of the remanent polarization (Pr) for the three series of samples. (E) Thickness dependence of the coercive field (Ec). (F) Thickness dependence of the coercive field distribution parameter δ extracted from the fitting of the hysteresis loops.
