In this work, the impacts of various pulsing schemes on endurance are comprehensively investigated. Trapezoidal and triangular waveforms are considered in endurance cycling tests. For endurance cycling with the trapezoidal waveforms, different rising time (Tr)/falling time (Tf), e.g., 0.05– $5 \mu \text{s}$ , with a fixed pulse width (Twidth) and different pulse width (Twidth), i.e., 0- $10 \mu \text{s}$ , with fixed rising time (Tr)/falling time (Tf) are used. As for the endurance cycling with the triangular waveforms, the frequencies are ranged from 1 kHz to 1 MHz. The results indicate that a shorter rising time (Tr)/falling time (Tf) results in a completely different endurance characteristic, and a longer Twidth leads to an earlier breakdown. Furthermore, the higher frequency of the triangular waveform results in a larger remnant polarization (2Pr) after endurance cycling. Overall, the endurance is highly dependent on the pulsing schemes, suggesting that a standardized methodology for the endurance evaluation is necessary for fair benchmarks and qualification of the ferroelectric-based technologies. |
