Abstract

Modified droplet epitaxy GaAs/AlGaAs single quantum dots have been studied by low-temperature magneto-photoluminescence spectroscopy. We observe Zeeman splitting and diamagnetic shift of the neutral exciton line. The Lande g factor of different quantum dots has been measured in a wide range of emission energies (i.e. quantum dot size). The measured g factors and diamagnetic shift are compared with conventional quantum dots grown by the Stranski-Krastanov method, as well as GaAs/AlGaAs quantum wells and fluctuation-induced dots.
