Figure 5
The calculated anisotropic transition probability Δ M and the average transition probability M . The vertical lines and arrows indicate the transition positions of 1H1E, 2H1E, and 1L1E. The inset shows the calculated energy band alignment of In0.15Ga0.85As/GaAs/Al0.3Ga0.7As step QWs with segregation length of indium atoms l = 2.8 nm and internal field F = 12.3 kV/cm. E c , E l h , E h h , and E s o represent the energy band alignment of the electron band, light-hole band, heavy-hole band, and the spin-orbit split-off band, respectively.
