James Kerfoot New Paper - Two-Dimensional Diffusion of Excitons in a Perylene Diimide Monolayer Quenched by a Fullerene Heterojunction James Kerfoot, supervisor Prof. Peter Beton and colleagues at the University of Nottingham have had a paper accepted in J. Phys Chem. C on exciton diffusion in monolayer organic materials in a collaboration with our Manchester group. In this new work, advanced AFM techniques are coupled to optical micro-spectroscopy to
