A method of nondestructive depth profiling in near surface regions of
solids is described. Models have been discussed from which algorithms
for evaluation of measured data are obtained. The algorithms, based on
standard profiles with free parameters, have been adjusted to the dat
a resulting from angle resolved XPS (ARXPS) by means of least squares
fits. Depth profile analyses and segregation studies were performed on
Pt-Ni and Fe-S specimens.
