Figure 3From: Optical properties of as-grown and annealed InAs quantum dots on InGaAs cross-hatch patterns PL spectra of samples (a) A [the controlled QDs] and (b) B [the controlled CHP]. The samples are subject to 700°C in situ annealing for 0, 10, and 30 min. Spectra are offset for clarity. Symbols in (a) are multiple Gaussian function fits.Back to article page
