Abstract

Using spectrally resolved femtosecond two-color three-pulse photon echo measurements we are able to study the dynamics of photo-excited carriers in near-spherical silicon quantum dots with an average size of 4.3 nm. The inhomogeneous broadening, dephasing time, and phase memory during carrier transfer can be obtained from this study.
