Project: Characterizing triboelectric interfaces with Atomic Force Microscopy (AFM) based methods
Supervisor: Prof. Dr. Thorsten Hugel
The triboelectric effect describes the following phenomenon: when two dissimilar contacting materials move in opposite directions, the difference in their electron-affinities causes charges to separate. However, for insulators, it is unclear whether electrons, ions or material fragments transfer during contact. In my research, I utilize Atomic Force Microscopy (AFM) with Kelvin Probe method to analyze the topography and surface potential of triboelectric interfaces before and after contacting. This approach will provide a better understanding of the relation between surface properties and triboelectric behavior.
