Figure 4From: Optical characterisation of silicon nanocrystals embedded in SiO2/Si3N4 hybrid matrix for third generation photovoltaics Absorption coefficient curves and Tauc plots. (a) Absorption coefficient curves in region 0 of Figure 3; (b) Tauc plot of region I with γ = 1/2. The dashed lines are fittings to the quasi-linear parts of the curves; (c) Tauc plot of region III with γ = 1; (d) Tauc plot of region V with γ = 2.Back to article page
