A researcher who coauthored light-emitting diode experiments using individual core-shell semiconductor nanowires with a transparent graphene contact. The contact supplied holes while allowing emitted light to escape. This combines a nanoscale emitting structure with an electrode whose electrical and optical properties must work together, a practical constraint in building small optoelectronic devices.[ref]
