| Abstract: | The carbon KLL first-derivative Auger spectra obtained by numerically differentiating the XPS N(E) line gives a better fine-structure fingerprint of the carbon state than conventional AES. The first-derivative of the X-ray excited (XAES) CKLL spectrum from a diamond-like-carbon (DLC) film exhibited almost the same spectrum as both the XAES and AES spectra from natural diamond. However, the AES spectrum of the DLC film indicated a graphite-like structure due to electron beam damage. Comparison of the XAES and AES spectra suggested that the electron beam used in conventional AES partially changed the plasmon loss structure of carbon in diamond, graphite and β-SiC as well. |
