The electronic structures of CdSe/CdTe type II colloidal quantum dots are predicted using a model based on k·pk·p theory and the many-particle configuration interaction method. The separation of energy levels in the conduction band is examined and us...

Ultrafast transient absorption spectroscopy is used to investigate sub-nanosecond exciton dynamics in CdxHg(1−x)Te alloy colloidal quantum dots. A bleach was observed at the band gap due to state-filling, the mono-exponential decay of which had a cha... Read More about Ultrafast exciton dynamics in CdxHg(1-x)Te alloy quantum dots.

Colloidal quantum dots (CQDs) are promising materials for solar cells because their optoelectronic properties are easily adjusted by control of their size, structure and composition. We present calculations of the band gap and radiative lifetime for...
