Abstract:

We report on optical studies of non-polar InGaN quantum dots grown on the (11$ \bar 2 $2) plane. Excitonic and biexcitonic complexes are identified by their power dependence and show similar binding energies (∼ 36 meV) and recombination dynamics to conventional polar (0001) InGaN quantum dots. Measured lifetimes as low as 300 ps suggest a reduced internal electric field when compared with polar InGaN quantum dots. Temperature dependent micro-photoluminescence measurements on a single exciton with a lifetime of 327ps reveal no significant exciton linewidth broadening up to 120K, suggesting a reduction in phonon coupling strength when compared to polar quantum dots. This is supported by a measured lifetime of 313 ps for this exciton at 77 K, suggesting the measured exciton decay is almost purely radiative. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
