Abstract

For resonant excitation of the ground state <TEX>$1s^e-1S^h_{3/2}$</TEX>, dynamics of 'the electron-hole pair in a CdSe quantum dot was investigated by degenerate pump-probe measurement. At low e-h pair densities, the decay of <TEX>$1s^e-1S^h_{3/2}$</TEX> state is dominated by radiative recombination. As the number of the electron-hole pairs increases, new decay features become significant. Theoretical comparison suggests this is attributed to the bi-molecular and Auger-type scattering.
