To get a quantitative value for the work function of a sample material you need to calibrate the AFM tip you are using. This is done by measuring a material with a known work function. We do not have a certified sample for this but we are using a sample that came with the system. it has some lines of Au-Si-Al right next to each other. The below image is from the Bruker application note: AN10-RevA1-PeakForce_KPFM-appNote.pdf
