| Outline of Final Research Achievements |
Highly efficient and high power Si-LEDs were fabricated by dressed-photon-phonon (DPP)-assisted annealing. It was found that Boron atoms, a DPP-creation source, formed a pair, and the separation between the two atoms in the pair was three-times the lattice constant of the Si crystal. The atom pair aligned along the plane normal to the direction of the incident light beam used for the annealing. It was also normal to the polarization direction of this light. Simultaneously with these experimental works, novel mathematical scientific model was developed to analyze the light-matter interaction in a mesoscopic space. The results of the analyses agreed well with the experimental results. Furthermore, statistical model of energy transfer in a random medium via dressed photons was developed.
