“…This finding can be used to differentiate, within minutes, whether a PL peak is shaped by the ensemble or the cavity, and prevent misjudgments regarding QD growth onto and into photonic dielectric heterostructures. A more thorough model will take the coupling to a charge reservoir [37] and the standing wave field amplitude into account. If the PL is found cavity-dominated and further investigation is desired, the sample can be subsequently characterized by cleaved-edge PL.…”

“…Reduced dimensions by constrictions on the nanometer scale in spatially tailored semiconductors lead to quantum confinement and large local density of states in a desired energy range, which is a huge advantage for many optoelectronic applications. One platform of such carrier confinement are self-assembled quantum dots (QDs), which enable research in fundamental solidstate physics [7,8] and quantum communication due to their excellent optical properties [9,10]. While the disadvantage of non-radiative recombination centers is obvious for optoelectronic devices, fluctuating charges in the environment of QDs are also unfavorable.…”
