Abstract
System and methods for decomposing an Auger electron spectrum into elemental and chemical components, includes conditioning and input spectrum to generate a normalized input spectrum; determining statistical correlation between the normalized input spectrum and stored elemental spectral signatures; and characterizing elemental or chemical species in the input spectrum from the statistical correlation, wherein said conditioning the input spectrum includes estimating a background signal of non-Auger electrons in the input spectrum and subtracting the estimated background signal from the input spectrum.
