Abstract In this paper, the third-harmonic coefficient in a bilateral rough Au-film percolation system deposited on the self-affine substrates is studied. It is proved experimentally that both the critical current and the film resistivity an functions of the third-harmonic coefficient yield power law critical behaviors. However, compared with flat systems, the critical exponents are significantly changed. The discussion for the universality behavior in this special system is also presented.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
