Epitaxially-grown three-dimensional Si/SiGe nanostructures produce photoluminescence and electroluminescence in the desired spectral range of 1.3-1.6 μm. We show that by controlling and modifying such Ge-rich SiGe nanoclusters during growth it is possible to fabricate very fast and hence more efficient SiGe light-emitting devices. Models for the physics of carrier recombination in these Si/SiGe nanostructures are presented, and a new route toward CMOS compatible light emitters is proposed.
