The recent discovery of a fundamentally different mechanism for electronic charge separation, which operates over a distance of a few nanometres and produces voltages that are significantly higher than the material bandgap has opened a new and promising research direction.

- photovoltaics beyond the conventional p-n junction. The recent discovery of a fundamentally different mechanism for electronic charge separation, which operates over a distance of a few nanometres and produces voltages that are significantly higher than the material bandgap has opened a new and promising research direction. This novel effect is driven by previously unobserved nanoscale steps of the electrostatic potential that naturally occur at ferroelectric domain walls and can be reversed in polarity or turned off. By working at the frontier of complex oxide materials science, this project aims to discover and implement new design approaches for electronic energy harvesting using nanostructured polar oxides for novel applications in optoelectronic devices.Read moreRead less
