Seeking a Postdoctoral Researcher

Research field and overview

The Quantum Optoelectronics Research Team aims at developing optoelectronic devices with novel functionalities by engineering devices that incorporate individual nano-materials. Such devices could allow for control over interactions between photons and electrons at the nanoscale, and may potentially be used for manipulation of quantum degrees of freedom, for example electron spins and photon polarization. We are particularly interested in developing quantum photon sources, quantum electroluminescence devices, and optical-to-electrical quantum interfaces.
