Figure 1From: Cooperative Effects in the Photoluminescence of (In,Ga)As/GaAs Quantum Dot Chain Structuresa AFM image of the uncapped (In,Ga)As/GaAs QD structure. b Fourier-transformed AFM image of an area with sizes 4 × 4 μm2. The arrows pointed out the maxima along the directions of the QD alignment, [0-11] and [011]; c Histogram of QD distribution by the aspect ratioBack to article page
