Semiconductor crystal miscut angles may be determined with high precision by a new method, based on the measurement of the Bragg angle shift for a highly asymmetric reflection. X-ray diffraction on a cleaved wedge has the particularity that the asymmetry is different for the cleavage plane and for the surface whose miscut angle is to be determined. Therefore, a rocking curve gives rise to two diffraction peaks. The angular difference between the two peaks is very sensitive to the miscut angle for high asymmetry of the reflection relative to the measured surface.
