Figure 5From: Optical Properties of GaAs Quantum Dots Fabricated by Filling of Self-Assembled Nanoholesa Micro-PL power series of a single type I GaAs QD from the sample of Fig. 4e with d f = 0.57 nm. b Zoomed part of the spectra. The laser energy was 1.96 eV, and the excitation power I e was varied from I e 8 up to 1,700 W/cm2. The red spectrum in (a) was measured using I e = 450 W/cm2, which is equal to the conditions applied in Fig. 4Back to article page
