摘要：
An analytical method has been developed for the measurement of a carbon depth profile of the region a few tens of mu m from the surface, using a (12)C(p, p'gamma) reaction. Measurements for a SiC sample coated with a silicon layer and a carbon-implanted silicon sample were performed using this method. Two charged particle detectors and two gamma-ray detectors were utilized for the coincident detection of scattered protons and gamma-rays from the first excited state (E(x) = 4.4 MeV) of (12)C. The measured depth profiles agree well with results obtained using a surface profiler and an Auger microprobe. These results demonstrate that this method is useful for the non-destructive analysis of carbon at depths of a few tens of mu m from the surface. (c) 2008 Elsevier B.V. All rights reserved.
