We are an interdisciplinary group focused on nanoscience for solar energy harvesting. We are interested in synthesis of novel nanoscale materials and in the behavior of photoexcited states in such systems.
A postdoctoral position is available in femtosecond spectroscopy of nanomaterials.
In a new publication in Journal of Physical Chemistry Letters, James et al study the temperature-dependent spatial dynamics of trapped photoexcited holes in CdS and CdSe nanorods, showing that trap-to-trap hole hopping behaves classically near room temperature while quantum aspects of phonon-assisted tunneling become observable at low temperatures.
In a new publication in Journal of Physical Chemistry C, James et al derive an easy-to-use equation for calculating the quantum efficiency of charge transfer exactly in donor–acceptor systems that exhibit nonexponential relaxation.
