Metric Options: CountsSelecting 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
Conductive LaNiO (LNO) buffer layers are grown on silicon and Pt-covered silicon and the effects on PbLa(ZrTi)O (PLZT) thin films are studied. The PLZT films on LNO-buffered Si and LNO-buffered Pt show different preferred orientations with the film on Pt. The LNO buffer layer not only induces the columnar growth of PLZT, but also reduces the surface roughness of the PLZT films. By introducing the LNO buffer layer on Pt, the PLZT thin film can achieve high polarization while reducing the window width of the hysteresis loop. The PLZT film on LNO/Pt exhibits the best energy storage performance in all samples. The recoverable energy density (W) of 15.66 J cm is obtained, which is 19% higher than the W of the PLZT film on LNO/Si and twice higher than the maximum W of the PLZT film on Pt. Moreover, the PLZT on LNO/Pt has an energy storage efficiency of 73% and exhibits better voltage stability. The nonlinear dielectric response results are used to analyze the different performances of the samples. This study suggests that the energy storage performance of the capacitors based on the antiferroelectric films can be further improved by adding the buffer layer on metal electrodes.
