Extended Data Fig. 2: Electrostriction Measurements.
From: Atomically engineered interfaces yield extraordinary electrostriction
a. Electrostrictive response of NGO/CGO/[ESB/CGO]7 under an alternating electric field. The strain developed at the second harmonic of the applied electric field. b. Field-induced stress as a function of the electrical field for NGO/CGO/[ESB/CGO]N measured at 1 Hz. The field-induced stress increases linearly with an increase in the squared electric field. No saturation was observed within the measured electric field range, regardless of the modulation length. The dash-dotted lines represent linear fittings of the measured results.
