Interfaces, charge-transfer and non-adiabatic processes and their exploitation in a frequency-tunable tribogenerator

Subproject

Simulation of Instabilities in the Adhesive Contact of Rough Elastic Bodies
Very sticky rough surfaces separate in an intermittent fashion: parts of the contacting area break off. These instabilities lead to adhesion hysteresis and friction and may play a role in contact charging. My simulations of contact mechanics complement the experimental investigations of Qiwei Hu and Ravi Divakar to correlate mechanics and charge transfer at the microscale.
