Abstract
Using spectrally resolved femtosecond two- and three-pulse nonlinear spectroscopy we study the dynamics and coherence properties of excited carriers in ZnO/ZnMgO quantum wells (QW) and silicon quantum dot (QD) structures embedded in silicon nitride (SiN). The contribution of biexcitons in ZnO/ZnMgO quantum wells at room temperature is identified. For Si quantum dots embedded in SiN a very short dephasing time of < 180 fs at room temperature is observed.
