    • We also observe spin coherence for temperatures higher than 100 K but then the dephasing times drop into the range of the trion lifetime. Several reasons may contribute: Besides fast hole scattering, electron scattering can be relevant as LO phonons become available, which may even lead to thermal emission of electrons so that the coherent signal may increasingly be contributed by neutral excitons. As no clear distinction is possible at the moment, we restrict to temperatures below 100 K.
