Li’s paper revealed charge carrier recombination and transport pathways as a function of excitation energy and stacking orientation. Great work Li! Thanks to Prof. Hua Chen in Physics for photocurrent simulations.
Colby developed an optically-detected electrochemical imaging technique to study Li-ion insertion processes in single nanoparticles. Optically detected cyclic voltammetry and chronoamperometry of single nanoparticles is quite different than nanoparticle clusters and the bulk.
