Fig. 62: RSM in the (h k = h L) reciprocal plane for several incident angles a. In (a) the penetration depth is about a few tenths Å, in (b), = 600 Å and in (c) is much larger than the total thickness, SL+Ir buffer. Fig. 62d shows a schematic representation of the contribution of SR1 and of SR2 centered on the (h1 h1 L) and (h2 h2 L) direction, respectively. The Miller indices are normalized to the fcc bulk Ir lattice.
