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.

Ultrafast charge dynamics in dispersions of monolayer MoS2 nanosheets (2017)
Journal Article
Kime, G., Leontiadou, M., Brent, J., Savjani, N., O'Brien, P., & Binks, D. (2017). Ultrafast charge dynamics in dispersions of monolayer MoS2 nanosheets. Journal of Physical Chemistry C, 121, 22415-22421. https://doi.org/10.1021/acs.jpcc.7b05631

Ultrafast charge dynamics in dispersions of MoS2 nanosheets in N-methyl-2-pyrrolidone are reported. Samples were prepared by the ultrasonication-assisted exfoliation of MoS2 powder, resulting in nanosheets that were predominantly monolayer and had an...

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...
