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
The transport properties of heterometallic n-alkanedithiol junctions have been investigated via first-principles calculations. Results show that the heterometallic n-alkanedithiol junctions exhibit significant rectification at lower voltage. A negative differential resistance was found at higher voltage, which increases with the increase of the n-alkanedithiol backbone length. In order to explain these phenomena, the molecular orbitals of n-alkanedithiol have been analyzed between certain electrodes. It is found that the rectification is induced by asymmetric orbital profiles between the heterometallic electrodes, and negative differential resistance arises when the molecular orbitals cross the band edge provided by the metal-sulfur bond.
