Vuong Van Cuong, Dinh Ba Khuong, Dao Van Lap

Abstract


We demonstrate that a two-colour three-pulsenonlinear spectroscopy can be used to study the dynamics of excited carriers inSi quantum dot structures embedded in SiN. Decays of the transverse optical phonon population and the transverse acoustic phonon population are measured and discussed. A simple theoretical modelis also used to support interpretation of our experimental observations.

Keywords


ultrafast spectroscopy; laser spectroscopy; optical properties of quantum dots
