Figure 2

This figure shows a schematic diagram of the model utilized to explain the excitation and subsequent relaxation in the Si-NCs following femtosecond pulse excitations. The vertical arrows indicate the direct excitation (a) and indirect phonon assisted excitation (b) of the carriers to the conduction band. The short vertical arrows (PA) pointing upward represent secondary excitations of the carriers by the probe pulse
