Controlled Generation of a p–n Junction in a Waveguide Integrated Graphene Photodetector
Controlled Generation of a p–n Junction in a Waveguide Integrated Graphene Photodetector
With its electrically tunable light absorption and ultrafast photoresponse, graphene is a promising candidate for high-speed chip-integrated photonics. The generation mechanisms of photosignals in graphene photodetectors have been studied extensively in the past years. However, the knowledge about efficient light conversion at graphene p-n junctions has not yet been translated …
