Figure 6

Influence of SD (a) A time series of consecutive single-NC spectra (offset for clarity) acquired at one specific spot; a transition between a type-Ia and type-Ic spectrum is evident. This series was measured at the same spot as the 20 K spectrum from Figure 4a, only with higher excitation power. (b) Average of the two lowermost spectra from panel a. (c) Simulated PL spectrum resulting from SD (black curve). The shaded gray curve is the input, “intrinsic” type-Ib spectrum, which underwent simulated SD; its main trionic line, including phonon replicas, is highlighted in red for easier orientation. (Panels b and c are to scale in the photon-energy axis.)
