... [30] was outlined to obtain in- plane subband dispersions in the valence band. Optical gain for transitions between subbands in conduction and valence bands is derived. Various scattering mechanisms ... interaction in inducing intersubband as well as intrasubband transitions. Among them, the 22ń11 process where both carriers originally in subband 2 end up in subband 1 is the...
