Silicon Nanocrystals: Fundamental Theory and Implications for Stimulated Emission

Figure 9

Fine structure of the energy spectrum with respect to the unperturbed sixfold degenerate energy level. Solid lines correspond to two states located in the Brillouin zone at the -point (001). Dashed line: -point (010). Dots: -point (100). The direction of the donor's position vector is defined by , , and . The NC radius is indicated in the figure.
