Figure 3From: Theoretical luminescence spectra in p-type superlattices based on InGaAsNTheoretical PL spectra at T =2 K for the same system described in Figure1. With fixed d1 = 3 nm for (a) N A = 2 × 1018 cm−3 and (b) N A = 6 × 1018 cm−3. The well width is varied for d2 = 2 nm (solid line), 3 nm (dashed line), 4 nm (dotted line), and 6 nm (dot-dashed line).Back to article page
