Figure 5
(a) RC of the 4H-SiC 0008 reflection: five diffraction conditions are marked. The difference between adjacent conditions is 2 µrad. (b) Images of the right-handed threading screw dislocation (first row) and the left-handed threading screw dislocation (second row) under conditions (1) to (5). The topographic image is on the left and the ray-tracing simulated image is on the right of each box. |
