Figure 3. Polarization-optimized ferroelectric switching at room temperature.
Electric polarization (P) versus electric field (E) hysteresis loops measured with a triangular ac electric field of various frequencies for (a) c-direction polarization of CRCA, (b,c) a- and c*-direction polarization of CBDC, (d) polarization normal to the plane of HPLN, and (e) c-direction polarization of ALAA. (f) A schematic waveform used for optimization in an endurance measurement mode.
