Abstract
The plasmon loss region of x-ray photoelectron spectra has been analyz ed for chemically vapor deposition diamond in order to assess the nond iamond carbon (NDC) levels present. A semiquantitative method for expr essing the quality of the diamond, based upon the ratio of the diamond bulk plasmon to the main carbon Is Line is presented and a figure of merit defined. A comparison with Raman spectroscopy shows that this te chnique compares well in terms of range and sensitivity to NDC levels. (C) 1996 American Institute of Physics.
