(a) First-order Bragg peak. The positions of the antinodes and nodes of the XSW formed within the first few layers (seven consecutive layers from the surface) of our graded Pt/Ni/C multi-trilayer are shown in (b) for the pristine ML and in (c) for the irradiated ML. The black curve corresponds to the angle chosen on the left-hand (lower angle) side of the Bragg peak while the blue curve corresponds to the angle chosen at the right-hand (high angle) side of the Bragg peak. |
