(a) RSM taken at 2.2 keV on InP wz nanowires grown on InP zb substrate using the PILATUS3 100K-M detector. The close XRD spots of the wz [002] reflection and the zb [111] one can be separated in the map. A (red) curve representing the count rate integrated along the Qy direction is superposed on the RSM. Qy is the component of the momentum transfer in the y direction (transversal to the X-ray beam), Qz is the component perpendicular to the surface. The inset shows a scanning electron microscopy image of the sample. (b) XRD θ–2θ scans performed in GI around the [100] reflection of the InP wz nanowires for different energies around the P K-edge. |
