What is work function of an insulating polymer (eg: Polystyrene ,PMMA etc..)? is it half of HOMO and LUMO? Do the ionization potential (IP) and Electron affinity (EA) change with work function?
IP= E(vacuum)-E(HOMO). So I guess this is always a constant. am I right?
But EA=E(Vacuum)-E(LUMO). Do this change with work function?
For example, if I bring the polymer in contact with gold, the work function change (modification in fermi level). Do this affect IP or EA? If so can anybody please tell me how it change?
