Master thesis defense by Anne Gladbo Platz

The existence of new current induced forces in molecular junctions has recently been shown. One having roots in the geometric phase this force is named the Berry force. Together with a non-conservative electron wind force the Berry force can lead to run-away modes at certain critical voltages causing the breakdown of the junctions.

This talk will present the Berry force and discuss the possibility to detect these run-away modes using Raman spectroscopy. We find voltage dependent Raman spectra where one mode will increase in temperature and one mode will decrease.
