Figure 3
Band profile (grey) and derived band edge positions (green vertical lines) given by the extrema of the first derivative (red curve) (Saowadee et al., 2017). The vertical dashed lines are the adapted Bragg angles for the first reflection orders. Ampl. describes the maximum amplitude of the profile. The Bragg angle (Th.ang.) and the asymmetry of the extremum positions (Th.cent.) displayed by the green lines are given in degrees. |
