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
Two-dimensional transition metal dichalcogenides (TMDCs) with direct bandgap and high optical absorption have opened a new horizon in photonics and optoelectronics. Increasing their absorption could greatly benefit their application, a subject still under debate. Thus, this study was focused on the plasmonic effect mediated by a thin gold layer and the role of individual spacer and cover layers or their combination in structures that include TMDC monolayers, namely, cover/TMDC/spacer/Au/substrate multilayers. The optical properties of these structures were investigated via the transfer matrix method in the visible wavelength region, revealing absorption values up to 99%. Such structures could be applied in the design of efficient optical absorbers for high-performance photovoltaic devices.
