Figure 4From: g-B3N3C: a novel two-dimensional graphite-like materialThe optical absorption expressed by the imaginary part of the dielectric tensor ε 2 for α - g -B 3 N 3 C. The imaginary part of the dielectric tensor is averaged for four different directions. Three XC potentials including (a) LDA, (b) PBE, and (c) MBJ are shown in the calculations.Back to article page
