Figure 5
Reflectivity curves from d = 22 Å (a) and d = 15 Å (b) W/B4C multilayers deposited on very smooth and well characterized Si (crosses) and on CVD SiC (triangles) substrates. For each pair of substrates, deposition was performed simultaneously within the same deposition cycle. MLs on SiC substrate show only slightly, ∼1%, lower maximum reflectivity. |
