Raman spectra obtained with a HORIBA Jobin Yvon confocal LabRAM HR800 spectrometer with the red laser line. The spectra are related to CVD diamond implanted with medium energy deuterium particles. As a consequence of this bombardment, amorphization of the diamond surface occurs and different sp2 carbon phases are created.
Window A : superposed spectra obtained by X-Y mapping (6 x 6 m squared shape) of the diamond surface. Magnitude of x100 was chosen for the microscope objective and the X-Y resolution was better than 1 m as seen on the picture.
Window B : typical spectrum showing the diamond Raman line at 1332 cm-1 and graphitic and disordered sp2 carbon around 1350, 1550 and 1600 cm-1.
Window C : 3D representation of the 1332 cm-1 peak intensity for the X-Y mapping.
Window D : 3D representation of the 1600 cm-1 intensity (sp2 graphitic carbon) (green cursors) for X-Y mapping. As it can be seen, this carbon phase does not match all the craters, shown on the window C. Complementary disordered amorphous carbon can be also observed by moving the cursors to 1350 or 1550 cm-1 region.
