Correct and incorrect peak Identification in EDS Measurements

WebEDS detectors have considerably lower spectral resolution than WDS spectrometers resulting in significant peak overlaps, higher dection limits, and lower accurancy and precision. However, for basic characterization and phase indentification, the technique is very powerful and requires very little set-up. WebMisidentifications can arise in automated peak identification procedures when only a single energy channel is used to characterize an EDS peak. The effect of the EDS measurement process is to convolve the closely spaced Lalpha-Lbeta and Malpha-Mbeta peaks into a single peak with a peak channel shift of 20 eV or more from the Lalpha or Malpha ... WebOct 1, 2024 · It was shown that the wave vector shift from the center of Brillouin zone, Δ q, leads to the shift of maximal frequency of vibrations Δ ω.
