The Feature Article by Jarjour et al. (p. 2510) reviews the progress made so far towards the development of optically excited and electrically driven single photon sources based on nitride-based single quantum dots. The back cover picture illustrates the emission of single photons in the blue region of the spectrum from an InGaN/GaN quantum dot under nonlinear optical excitation in the near infrared. The atomistic structure of an InGaN quantum dot embedded in a GaN barrier was used in the atomistic simulation of the electronic structure of these quantum dots. The correlation measurements shown in the graph demonstrate the single-photon nature of the emission.
