WebJan 13, 2024 · The work function converges towards the value of graphite as the number of layers is increased. Thereby, n-type doped epitaxial graphene layers have a work function lower than graphite and p-type doped quasi-freestanding graphene layers exhibit a work function higher than graphite. We explain the behaviour by the filling of the … WebAccording to them, the work function of rGO can be tuned up to ∼2.5 eV by varying the composition of oxygen-containing functional groups. Sygellou et al. 12 studied the variation in work function of GO via three different reduction processes. They found the work function decreases by ∼1 eV between GO and reduced GO.
WebApr 23, 2010 · Secondly, we show that the reduced work function originates from the charge depletion in the graphene skeleton states at bonded carbon atoms, in contrast to the assumed n-doping of π states. ...

WebMar 6, 2013 · But the integral function starts to fall apart after 6 hours, as in the problem pictures above show, because of how Graphite aggregates data. How Integral Breaks The integral function sums things.
WebWork function. In solid-state physics, the work function (sometimes spelt workfunction) is the minimum thermodynamic work (i.e., energy) needed to remove an electron from a solid to a point in the vacuum immediately outside the solid surface.
