Abstract
The electron states in silicon quantum wires obtained within an effective approximation are used to study the spontaneous emission rate for direct and phonon-assisted transitions. It is found that light emission from the wires has strong direct character if the wires are directed along the main crystallographic directions or along [110]. The intensity of phonon-assisted transitions is in this case three orders of magnitude smaller.
