| Abstract(in English) | Carrier transition processes via deep states leading to the reduction of the band edge radiative recombination efficiency have been analyzed by infrared (IR) spectroscopic measurements. We focus on the thermally activated non-radiative recombination (NR), radiative transition via deep states, and carrier transportation processes by NR defects. Although we have found the radiative recombination via deep states, the dominant carrier recombination processes is NR by phonon emission processes. Candidate defects of the NR centers are accepter nature. The difference in the PL intensity between n and p-type samples are caused by the difference in the minority carrier diffusion length and effective NR activation energy in the configuration coordinate diagram. NR rate in InN is highly affected by the carrier transportation and thermal activation processes. |
