Fig. 1From: On the switching dynamics of epitaxial ferroelectric CeO2–HfO2 thin film capacitorsa, b Polarization-field hysteresis loops and c, d cycling experiment for the sample annealed in N2 atmosphere and sample annealed in O2 atmosphere, respectively. Coercive fields are depicted as grey closed symbols, remanent polarizations as orange open symbols. Coercive fields at measured cycling stages are indicated as star symbolsBack to article page
