The modeling, moreover, allows us to differentiate the interband absorption according to transitions at the X -and L-points (red dashed and yellow dashes). The comparison of the two separate contributions to the data clearly shows that absorption at both points is necessary to reproduce the PLE spectrum. This is insofar surprising as the vanishing shortwavelength emission implies that direct emission at the L-point is suppressed. The presence of L-point absorption in the PLE spectrum therefore requires that the system undergoes some form of internal conversion process, e.g. by Auger-scattering, before recombination.
