Fig. 4: Ultra-low coercivity of HZO(100)O/STO(110) films.
From: Interface-controlled uniaxial in-plane ferroelectricity in Hf0.5Zr0.5O2(100) epitaxial thin films
tHZO-dependent coercive fields (EC) derived from the HZO(100)O/STO(100) films with various tHZO. A series of tHZO-EC curves extracted from references are also inserted for comparison. The tHZO-EC curves of epitaxial (polycrystalline) HZO films are plotted in solid (open) symbols for clarity. The EC \(\propto\) (tHZO)−2/3 relationship is marked by a dash-dot line.
