Abstract :
We present the results of various femtosecond pump-probe spectroscopies on quantum confined Si and Ge nanocrystals. The spectroscopies include femtosecond hole burning, differential transmission, and pump-probe decays. The experiments were performed with a Ti:sapphire regenerative laser amplifier
