“…Our results for the reflectivity of graphene are in very good agreement with other calculations. 17 Furthermore, our calculation of the reflectivity of LN is in good agreement with experimental results. 16 Usually, the positions of the peaks are practically the same as the corresponding to the imaginary part of the dielectric function.…”

“…Furthermore, refractive index of a structure can be calculated in terms of dielectric functions, i.e., n(ω) = ( ε 2 1 (ω) + ε 2 2 (ω) + ε 1 (ω)/2) 1/2 . For the pristine SnC, static refractive index, n(0) is found to be 1.65 which is higher than the refractive index of single-layer graphene (n(0) = 1.1 [61]). In the presence of applied strain, the tensile (compressive) strain increases (decreases) the refraction index as n(0) +2.5% = 1.75 and n(0) +5.0% = 1.93 (n(0) −2.5% = 1.58 and n(0) −5.0% = 1.52).…”

“…The static parallel refractive index n k ð0Þ ¼ 1:44 for monolayer blue phosphorus comparable with graphene (n k ð0Þ ¼ 1:12 and n ? ð0Þ ¼ 2:75) [46] and 2D-ZnS (n k ð0Þ ¼ 1:66) [47]. The main peak values of refractive index for monolayer, AA and AB stack bilayer blue phosphorus are 2.79 at 3.60 eV, 3.17 at 3.70 eV, and 3.75 at 3.60 eV, respectively.…”
