Lognormal Distribution of Pore Areas for AQ on Au(111)

For anthraquinone (AQ) on Au rather than Cu(111), we find no giant honeycomb network or chain formation, just small hubs of three AQ pairs [1]. This behavior is shown to be consistent with the explanation of the giant regular network on Cu in terms of surface states populating close-shell 2D orbitals [2]. For higher coverage large irregular vacancy pores have a lognormal area distribution indicative of multiplicative noise, in contrast to less-skewed distributions found for capture-zone areas. Lognormal distributions have also been found for county-like secondary administrative units in a minority of countries, e.g. ilceler in Turkey and gemeenten in Netherlands [3].
