αf/αc (αc = 0.22° for Ge) curves collected after growth at 740 K. The peak integration was performed using another ROI having the size of 20 (H) × 20 (V) pixels, corresponding to a detector acceptance of 1.7 mrad in both directions centered at the pixel position of the Ge substrate Yoneda peak αc. The X-ray diffraction patterns as a function of the exit angle are collected in a way that the diffracted signal is always hitting the same detector pixel position. |
