Micro Abstract:
Efficient technologies for energy harvesting are in the focus of recent research. Our nanogenerator transforms parasitic mechanical oscillations into usable electric energy. If an electric field exists between electrodes, leakage currents appear if the ferroelectric ceramic is semiconducting. We focus on different formulations of leakage currents for semiconducting ceramics, usually given as scalar equations. We enhance our phase field model to account for these effects in space.
