Time-integrated PL intensities. Ι1 (an open blue triangle), Ι2 (an open green circle), and Ι3 (a closed red square) of the individual decaying components with the decay times τ1, τ2, and τ3, respectively, as a function of temperature in the Si ND array with the SiC barrier (a). Solid blue and green lines are calculations using a three-state model. A dotted red line is the guide for the eyes. A schematic illustration of the three-level model used in the analysis for the temperature dependences of PL intensities of time-resolved I1 and I2 components (b).
