    • The exciton states discussed are those with a 1s in-plane wave function, as these dominate the NIR spectra. The subtends h1 and h2 are "heavy hole" subbands because of their high effective masses. Excitons formed from the valence subbands with a lighter effective mass ("light hole" subbands) are shifted to higher energies as a result of strain and do not appear in the measured spectra. Excitons associated with higher subbands (e2, h3) are sufficiently far away in energy that they should only weakly couple to h1X.
