[SOLVED] Work Function .- Does anybody know a reference for an intuitive model of the work function? If not, is there a simple quantum mechanical model for it? .- Does anybody know of a simple model for a solid - electrolite interface?. .- What about a metal - metal interface?. .- I'm looking for an intuitive or mechanistic model of electron displacement (transport) at the interface of two metals in orden to explain potential diferences between them.
