(a) A plot of standard electrode potential against work function of 11 contact metals used.The bars in green region within 4.26–4.33 eV of work function and in pink region within 4.95–5.15 eV. In the two regions the contact resistances are plotted against standard electrode potential respectively (b and c). The bars in orange color are used for a guide to eyes.
