摘要
We report on the analysis of the carrier dynamics in GaNAs by femtosecond pump-probe spectroscopy at different wavelengths. GaNAs with dilute N concentrations below 2% are prepared by ion implantation and NME growth. The implanted and annealed samples reveal carrier dynamics dominated by traps, while in the MBE grown samples distinct relaxation dynamics are observed which are associated with the modified band structure.
