| Year of publication: | 1997 |
| Published in: | Applied Physics Letters ; 71 (1997), 19. - pp. 2779-2781 |

| Summary: |
We investigate the relaxation dynamics of photogenerated carriers in low-temperature grown GaAs by femtosecond pump-probe measurements. The carrier dynamics in the vicinity of the band edge is disentangled in a two-color technique. The filling of shallow bound states close beneath the band edge is resolved. A temporal delay in the occupation of these states as well as a large optical nonlinearity points towards microscopic potential fluctuations forming these states.
