Testing Function
Polarization-Electric field (P-E) hysteresis loop measurement is the quintessential technique for identifying spontaneous polarization, coercive electric field (Ec), and remanent polarization (Pr) in ferroelectric materials. Utilizing high-voltage biphasic drives up to ±10 kV and PUND (Positive-Up-Negative-Down) pulse protocols, our laboratory cleanly separates true domain switching polarization from parasitic resistive leakage, delivering rigorous data for ferroelectric memories, actuators, and capacitive energy-storage ceramics.
