Near-surface-layer analysis by x-ray fluorescence critical takeoff-angle detection was examined theoretically and experimentally. The takeoff-angle dependence of Cr K-L x-ray fluorescence from Cr thin films was measured with practical analyzed depth varying from several thousand to less than one hundred angstroms. Comparison of Cr K-L and K-M takeoff-angle dependence shows the analyzed depth depends on the observed x-ray energy even with identical takeoff angles. The potential of nondestructive depth profiling is also discussed.
