Upper part: optical micrograph of the Mg-rich hexagonal pyramids in GaN and blue-red plot displaying the Cr/Fe K[alpha] intensity distributions with their corresponding concentrations in the colour scales. Lower part: calculated and measured XANES data around the Ga K-edge for perpendicular/parallel incidence on the pyramid centre and outside it, as well as calculated and measured XLD also recorded at the Ga K-edge with the beam focused on the pyramid centre and outside it.  [article HTML]
