Figure 4
2Θ–Φ mapping of the Si 200 reflection near the [011] in-plane direction measured (a) in high-resolution and (b) in low-resolution mode. The dotted structure of some streaks is caused by the finite step widths of 0.02 and 0.1° for 2Θ and Φ, respectively. The bar between ΔΦ = ±2.5° marks approximately the Φ range within which the measurements shown in Fig. 1 were performed. |
