Figure 6
(a) A 2D detector image of the GaN 204 Bragg peaks at one position in the GaN structure, with the x and y axes representing Φ and 2θ, respectively. Intensity is displayed to the right of the image and two Bragg peaks at different values of Φ are shown with the red arrows. (b), (c) Rocking curves showing two Bragg peaks at different values of ω for (b) p = 0.5 µm and (c) p = 1 µm. |
