Abstract

An internal calibration method for Auger spectra of binary alloys is proposed. It comprises the in situ breaking of pre-notched, homogenized, alloys rods in ultrahigh vacuum and the immediate analysis of the fracture surface. An investigation of a wide range of compositions of each of the alloys PtSn, AgAu, AuSn and AgSn shows that the observed signal intensity ratio is proportional to the corresponding atomic ratio of the elements present, which would suggest that matrix effects do not play an important role.
