Abstract
A semiconductor optical emission device comprising a layer of material containing a plurality of stress variations and adhering to a surface of a semiconductor is described. In one embodiment the semiconductor is an indirect band gap semiconductor and is silicon in one aspect, the material of the layer comprises silicon and metal oxides and is prepared by a sol-gel process including thermal annealing in one aspect. The layer urges a plurality of randomly distributed elastic deformations in the semiconductor that substantially enhances the radiative recombination interactions among free carriers in the semiconductor.
