Ultra Electron Density Sensitivity for Surface Plasmons
Wei Liu, Meng Li, Yu Niu +1
We investigate surface plasmons from a solid-state standpoint and highlight their ultra electron density sensitivity. When a surface plasmon is excited on a planar gold film by an…

Direct imaging of single-molecule electronic states in chemical reactions
Wei Liu, Meng Li, Houqiang Teng +4
Current single-molecule imaging techniques are incapable of providing stochastic information of individual chemical reactions. We have developed an optical imaging method for stoch…
