|Title:||Effects Of The Heavy- And Light-hole Mixing In The Exciton Dynamics In Semiconductor Quantum Wells|
|Abstract:||We present the calculation of the low temperature exciton bimolecular formation rate in quantum wells through acoustic phonon scattering taking into account the heavy- and light-hole mixing in the hole and exciton states. We observe a decrease in the exciton formation rate compared to the parabolic approximation. For symmetric quantum wells, the hole-subband mixing allows a finite probability of scattering involving the change of parity. This opens a channel for spin-flip transitions during the exciton formation process.|
