Figure 4From: Optical properties of as-grown and annealed InAs quantum dots on InGaAs cross-hatch patterns PL spectra of sample D, and changes in integrated intensity and FWHM. (a) PL spectra of sample D [QDs on CHP] subject to 350°C ex situ hydrogen annealing for 0, 30, 60, and 120 min (offset for clarity). Changes in (b) integrated intensity and (c) FWHM of the main emission peaks as a function of annealing time.Back to article page
