Fig. 1. (Color online) (a) Conduction and valence band profiles with squared envelope functions for electrons (|Ψ1|2, |Ψ2|2) and holes (|ΨH1|2, |ΨH2|2). (b) Optical recombination scheme for transitions from first and second subbands to localized state (Eloc.h) and/or heavy-hole subband (E1H1, E2H1) and from Fermi-energy level to localized state (FES).
