Figure 6
(a) Simulated spatially resolved rocking curve of a slice of the diamond crystal away from the stacking fault using an aberrated model of the condenser lens. (b) Measured spatially resolved rocking curve of a slice of the diamond crystal away from the stacking fault. (c) Measured and simulated spatially integrated rocking curves of a diamond single crystal in the region containing a single stacking fault. (d) Sketch of the scattering geometry in reciprocal space in the laboratory frame. The incident beam consists of a continuum of rays of different k0 vectors (blue rectangle); due to the divergence and finite bandwidth of the incident beam, this smears out the Ewald's sphere to a shell. For a given rotation of the crystal only points on the dotted line (the bisection of the Q vector) satisfy the Bragg condition. When the crystal is rotated by an angle ϕ (thereby rotating Q into Q′), this line is moved and a different part of the incident spectrum satisfies the Bragg condition. This leads to scattering in a different direction in the laboratory frame (comparing red and pink arrows). |
