Abstract

A femtosecond pump-probe setup was used to measure the time resolved reflectivity of hydrogenated amorphous silicon containing crystalline silicon nanoparticles at eight different incidence angles. Results fitted with the Drude model found a scattering rate of Γ = 2 × 10 s at a corresponding carrier concentration of ∼10 cm . The observed scattering rate is attributed to enhanced carrier-carrier interaction in optically pumped nanocrystals.
