Silicon Nanocrystals: Fundamental Theory and Implications for Stimulated Emission

Figure 18

Left: Plot of a simulation box, 4000 NCs, initial state. Dark clusters contain one or more defects. Right: multilayered sample in a time window between 50–100 𝜇s after the end of the pump pulse. Yellow NCs had a radiative recombination event during this time period and white NCs have no charge carriers remaining. Interaction effects were turned off for these simulations. The orange NC in the lower left corner of both images is 5 nm in diameter.
