Figure 8
Energy-dependent reflectance (double reflection) at different positions (pores) of the MM. In the linear plot (a), the Ir M edges are clearly visible. As the incidence angle for plates 25 and 17 are slightly steeper (0.822° and 0.829° instead of 0.814° for plate 33), the reflectance decreases faster towards higher energies. From the position of the maximum and minimum in the logarithmic plot (b), an Ir layer thickness of about 10 nm can be confirmed. The calculated reflectance using the nominal values and optical constants from the literature (Henke et al., 1993BB11) is shown as a dashed line.
