Figure 5. (A) P-E hysteresis loops and (B) I-E curves at 10 Hz of the xSm ceramics with a thickness of ~0.3 mm. (C) P-E hysteresis loops under different electric fields at 10 Hz of the 1.0 Sm ceramics with a thickness of ~0.25 mm. (D) d33 value and optical transmittance (at ~900 nm) of the xSm ceramics. (E) P-E hysteresis loops under different temperatures at 10 Hz of the 1.0 Sm ceramics with a thickness of ~0.3 mm. (F) The comprehensive performance comparisons of the 1.0 Sm ceramic with other representative KNN-based transparent ceramics.
