Quantitative investigation of plasmonic hot-electron injection by KPFM
Applied Surface Science, 2019 Abstract Hot-electron injection is widely used in plasmonic devices. However, it is still lack of a direct theoretical model for performance prediction. This paper measures the surface potential of Au/TiO2 film by Kelvin probe force microscope (KPFM) under various conditions, and then develops a theoretical model for quantitative interpretation.

The role of the cantilever in Kelvin probe force microscopy measurements
Beilstein Journal of Nanotechnology, 2011 The role of the cantilever in quantitative Kelvin probe force microscopy (KPFM) is rigorously analyzed. We use the boundary element method to calculate the point spread function of the measuring probe: Tip and cantilever.
