Available in PDF, EPUB and Kindle. Book excerpt: Self-organized InAs/GaAs quantum dot bilayers with nearly perfect size distribution have been grown and characterized. A record small photoluminescence linewidth of 17.5 meV is measured at 300 K, which is almost identical to that measured in the emission from a single dot, indicating that the linewidth is determined by homogeneous broadening.
