The inset shows the broadening of the diffraction peak because of low structural uniformity. Concerning the Mo/B PMMs, even the PHA-543613 Technical Information expected reflectivity of 503 was nonetheless smaller than the theoretical maximum, which was about 70 . This difference in reflectivity was attributed for the formation of interlayers, higher interface roughness, and terrible structural uniformity. The first two elements decreased the sharpness of interfaces between Mo and B inside the periodical stack. These things led for the reduction of reflectivity. The structural uniformity implies the regularity on the thickness from the layers and interface structure across the whole multilayer stack. Apparent errors within the thickness of individual layers or their continuous variation (drifting) caused by a variety of components deteriorate the uniformity. Preserving structural uniformity is essential for sustaining Bragg’s diffraction condition. The nature of your periodicity is defined primarily by the deposition rate’s time stability and upkeep with the substrate temperature [24]. The degree in the uniformity is usually rapidly evaluated by low-angle X-ray reflectometry [44], and manifests itself in the form of broadening of diffraction peaks, as shown in Figure six. The real structure suffers from the gradual improve within the interlayers on account of the raise within the substrate temperature through the deposition.
