Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
For high-power on-resonant piezoelectric applications, piezoelectric materials with high piezoelectric coefficient ( d 33 ) and mechanical quality factor ( Q m ) are in high demand. However, previous work has shown that the d 33 and Q m are generally inversely proportional, implying that it is difficult to improve these properties simultaneously. Here we report the simultaneous enhancement of d 33 and Q m in (Mn, Zr) co-doped BaTiO 3 (BT- x Mn- y Zr) ceramics. Compared with pure BaTiO 3 ceramics, the piezoelectric coefficient ( d 33 ) of BT-0.5%Mn-5%Zr ceramic is increased from 190 pC/N to 321 pC/N, and the Q m is increased from 290 to 513. Furthermore, the Q m of BT-1%Mn-5%Zr ceramic reaches 1470, and the d 33 is 248 pC/N. When both d 33 and Q m are considered, the obtained properties outperform commercial hard Pb(Zr,Ti)O 3 and other typical lead-free ferroelectric ceramics. The experimental results show that the enhanced d 33 and Q m of these ceramics originate from the synergistic effect of defect engineering-induced domain configuration effect and pinning effect. This work provides insights into the design of high-performance high-power lead-free ferroelectric materials.
