Stranski–Krastanov mode growth yields QDs with heterogeneous size, shape, and inter-dot spacing, which can contribute to broadened emission spectra and diminished quantum efficiency. Therefore, elucidation of the emission dynamics and carrier relaxation pathways is important. In this study, time-resolved photoluminescence measurements were conducted to investigate carrier relaxation dynamics within the green InGaN QDs, underpinned by the hypothesis of interdot tunneling-mediated carrier transfer.
