Silicon Nanocrystals: Fundamental Theory and Implications for Stimulated Emission
Figure 2
Experimental data on the size dependence of the optical gap of silicon crystallites.
Hydrogen-passivated surface—Wolkin et al. [8] and Garrido et al. [53] (blue squares); SiO-bonds at the surface—Wolkin et al. [8], Kanemitsu et al. [51] (diamonds);
deposition on quartz substrate—Ledoux et al. [48] (filled triangles); nanocrystals embedded in matrix—Kim et al. [49] (empty triangles).
