Figure 7From: Long-wavelength room-temperature luminescence from InAs/GaAs quantum dots with an optimized GaAsSbN capping layerPL spectra at 15 K for samples with different Sb and N contents. PL spectra when increasing the flux of Sb and N during the growth of the CL at (a) 2.0 ML s−1 and (b) 1.5 ML s−1.Back to article page
