Figure 9From: Characterization of Er in porous SiCorrelation of the shifts on the Er-doping level. ΔR (right axis, blue empty triangles) and Δλ (left axis, red full triangles) plotted as a function of the nominal Er content for a series of 1.25-μm-thick PSi samples. The lines are intended only as guide for the eye. For the definition of ΔR and Δλ, see Figure8.Back to article page
