The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 1.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 1.3 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 2.2 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00034 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.46 SJR: 0.333 SNIP: 0.606 CiteScore™:: 3.1 H-Index: 31

ABSTRACT

In this work we study the effect of the substrate vibration on the atomic-scale sliding friction using Tomlinson model. By actuating substrate sub-nanometer vibration parallel to the sliding direction, we find the stick-slip motion can be largely suppressed, resulting in very low sliding friction. The vibration of the substrate will actuate the relative vibration between the sliding tip and the substrate, which will help the tip overcome the substrate surface potential barrier. This mechanism is different from the previous vibration method by actuating vibration perpendicular to the contact surfaces. Our simulation results show that the frequency and amplitude of the substrate vibration are two critical parameters for the friction reduction. Through modulating the vibration frequency, the tip motion can change from stick-slip to continuous sliding, which leads to nearly zero sliding friction. The range of the zero-friction frequencies is determined by the fundamental vibration frequencies of the sliding system. In order to achieve high friction reduction effect the amplitude of the substrate vibration should be larger than one fourth of the period of the surface potential. This work will benefit the design of nearly friction-free interface.
