The actual work function is VERY dependent (usually) several factors including morphology, preparation, gas on surface, oxidation. Aluminum is a strange one. Once exposed to atmosphere the surface oxidizes and the effective work function increases to values of 10 or 11 ! Most common metals can be roughly assumed to have a work function of 4.5 专心-专注-专业
