Figure 4
Rocking-curve (θ–2θ) scan of the In/AlAs superlattice sample (red) compared with the theoretical simulation of the design geometry (black). Here, the `SL-alloy' peak is likely caused by scattering from mixed InxAl1–xAs layers (with x ≃ 0.8) at the InAs/AlAs interface. A schematic overview of the sample geometry is shown on the right. qz is the out-of-plane component of the scattering vector.
