Figure 3

RD spectra of 5 nm-In 0.2 Ga 0.8 As/GaAs QW under different strain ϵ xy in unit of e 0 = 3.23 × 10 -5. The spectra are measured at room temperature and shifted vertically for clarity. The oblique lines indicate the energy positions of the transitions 1e1hh, 1e2hh, and 1e1lh in the RD spectra.
