Abstract

Here we report results obtained using two-dimensional photon echo spectroscopy (2DPE) to study ultrafast dynamics in CdTe/CdSe heterostructured quantum dots. From these measurements we are able to extract "peak shift" information usually obtained by homodyne three-pulse photon echo peak shift measurements. Additionally we are able to observe how absorptive features in the 2DPE spectrum beat in an anticorrelated fashion at the frequency of the LO phonon modes of the nanocrystal.
