Research Interests

Research in the Hartland group is focused on using optics to examine the properties of nanomaterials and how these materials interact with their environments. Almost all the projects in the group involve single particle studies, and the development of novel techniques to perform time-resolved and steady state spectroscopy experiments on single particles is a major component of the research. Examples of the processes that are being studied are the propagation of surface plasmon polaritons in metal nanostructures, charge carrier trapping and diffusion in semiconductor nanowires, chemical reactions in nanomaterials, and the effects of viscosity at the nanoscale.
