Figure 2From: Cooperative Effects in the Photoluminescence of (In,Ga)As/GaAs Quantum Dot Chain StructuresNormalized PL spectra for the multilayer In0.4Ga0.6As/GaAs QD chain sample measured at different temperatures. For clarity, the spectra are vertically shifted with respect to each other. Two Gaussians best fitting the PL spectrum measured at T = 150 K are shown by dashed linesBack to article page
