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
Paracostibite (CoSbS) has recently been identified as a promising thermoelectric (TE) material, yet its full potential remains to be attained. We present herein an integrated method based on high throughput DFT computations validated with experiments that has allowed us to identify tellurium on antimony sites as a much more effective dopant than the formerly used nickel on cobalt sites. By carrying out a systematic adjustment optimization of the experimental parameters, we achieve a power factor as high as 2.7 mW m K at 543 K, which is maintained up to 730 K. This is, to the best of our knowledge, the largest value reported for polycrystalline metal sulfides.
