Silicon Nanocrystals: Fundamental Theory and Implications for Stimulated Emission
Figure 7
NC gap versus reciprocal dot radius. Solid line: infinite barriers (21). Circles: finite barriers (3.2 eV for electrons and 4.3 eV for holes, which corresponds to Si/Si interface) and constant effective mass. Disks—finite barriers and free electron mass outside the dot. Both of the latter are numerical results by EFA [92]. The dashed line is a guide to the eye.
