中文摘要	in this study, we report comparative luminescence properties of multi-layer ingan quantum dots grown on c- and r-plane sapphire substrates by metal organic chemical vapor deposition (mocvd). high-density ingan quantum dots (qds) are formed on gan templates by decreasing the growth temperature and increasing the adatom hopping-barrier through surface passivation. atomic force microscopy (afm) has been employed to estimate the size and height of these dots. photoluminescence (pl) spectra recorded from (1120) ingan qds/(1102) sapphire show much stronger emission intensity compared to spectra recorded from (0001) ingan qds/(0001) sapphire. due to the absence of strong spontaneous polarization and piezoelectric field, such (1150) ingan qds in the active layers would lead to high efficiency light emitting devices.
