Colloidal quantum dots (CQDs) are semiconductor crystals, the nanometre-scale size of which both allows their absorption edge to be controlled during growth and enhances the yield of multiple exciton generation. These properties, combined with the fa... Read More about Charge dynamics in colloidal quantum dots : recombination, trapping and multiple exciton generation.

The passivating effect of cadmium in PbS/CdS colloidal quantum dots probed by nm-scale depth profiling (2017)
Journal Article

Achieving control of the surface chemistry of colloidal quantum dots (CQDs) is essential to fully exploit their properties in solar cells, but direct measurement of the chemistry and electronic structure in the outermost atomic layers is challenging....

Multiple exciton generation and dynamics in InP/CdS colloidal quantum dots (2017)
Journal Article

We report measurements of multiple exciton generation and recombination in InP/CdS (core/shell) colloidal quantum dots. Ultrafast transient absorption spectroscopy was used to measure the subnanosecond charge dynamics for a range of pump fluences and...
