Table 1. Structural parameters of the synthesized Mo/B4C structures.
d is the period of the structure in Å, R is the reflection coefficient in the first Bragg peak at a wavelength of 1.54 Å in %, N is the number of periods, σMo is the width of the B4C-on-Mo interface in Å, σB4C is the width of the Mo-on-B4C interface in Å, Δλ/λ is the spectral selectivity in the first Bragg peak in %, R* and Δλ/λ* are the calculated reflection coefficient and spectral selectivity in % in the first Bragg peak with zero period drift.
