| Table I. Measured atomic percentages from Auger spectra on SAMs covered by Al2O3 deposited via ALD (10 cycles), individual spectra are shown in Ref. 20. Spectra from samples without a SAM show no sulfur and only a weak carbon signal. ODT, MUD, MUA, and 4-mercaptobenzoic acid (MBA) all have strong sulfur and carbon peaks. All spectra were taken with a 20 kV, 10 nA beam on a PHI 700 scanning Auger nanoprobe. | |||||
