| Outline of Final Research Achievements |
We have developed methodology of electron-phonon interaction analysis in crystal with singularity, and established a basis of analysis of phonon-electron-photon system in surface structures and defective fields. (1) For physical properties of phonons, a vehicle for three-dimensional phonon transport analysis has been established by Raman imaging using double lasers. Using this method the effects of misfit dislocation in the vicinity of heterointerface on phonon transport has been revealed. (2) Theoretical analysis method of phonon-exciton-radiation system has been established. Experimental analysis using phonon replica emission has been conducted, and a methodology to analyze emission dynamics of carriers has been proposed.
