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 field emission (FE) of surfaces of highly oriented pyrolytic graphite (HOPG) UPV-1T and glassy carbon SU-2000 after irradiation with 30-keV Ar ions at different temperatures and incidence angles has been investigated. It has been found that irradiation of the (001) basal plane of UPV-1T at temperatures of T = 250 and 400°C results in the emergence of low-voltage FE with threshold values of the electric-field strength from 3 to 17 V/μm depending on the temperature and irradiation geometry. The lowest field-emission threshold is observed following irradiation at T ≈ 250°C and normal ion incidence. It is shown that ion irradiation of glassy carbon can also result in the low-voltage FE of its surface. © 2013 Pleiades Publishing, Ltd.
