[16p-B508-4] Demonstration of remnant polarization enhancement in HfO2 thin films induced by polarization switching under mechanical tensile strain
Keywords:ferroelectricity
The effect of structural strain on the expression of ferroelectricity and the variation of the magnitude of polarization in HfO2 was directly verified by applying mechanical strain by four-point bending. It was shown that the ferroelectric phase is strongly induced by ~0.1 % of tensile strain. The results also support the model that the magnitude of waking-up increases with tensile strain.
