Structural evaluation of GaN/sapphire grown by epitaxial lateral overgrowth by X-ray microdiffraction
The cover picture from the article  depicts the geometry of X-ray diffraction on a GaN/sapphire structure made by a two-step epitaxial lateral overgrowth (2S-ELO) process. Below, the X-ray rocking curve as a function of the vertical beam position in 2S-ELO GaN/sapphire is shown. A low intensity line diverging from the main peak position (arrow) may be interpreted as the disappearance of a winged crystal region due to dislocation curvature.
