Rezumat

Low temperature grown GaAs (LT-GaAs) became one of the most important materials for ultrafast optical and THz devices. In this paper we study influence of δ-Si doping on carrier dynamics  of LT-GaAs. Investigation was carried out by means of optical “pump-probe” spectroscopy. Non-equilibrium carriers were injected by femtosecond pulses generated by a Titane:Sapphire laser at 800 nm, which falls above the band gap of GaAs. Transient reflectivity on the same wavelength was detected.
