3D Raman image of 3C-SiC core inclusion (jpg)

3D Raman image of 3C-SiC core inclusion, showing: 3C-SiC inclusion (red); 4H-SiC epilayer (green); 4H-SiC substrate (blue). A pipe-like structure leaves the main inclusion at a slight angle to the substrate. This pipe is subsurface and would be difficult to locate using other techniques.
