      Graphene is a promising material for ultrafast and broadband photodetection. Earlier studies have addressed the general operation of graphene-based photothermoelectric devices and the switching speed, which is limited by ...

    • Ultrafast electronic readout of diamond nitrogen-vacancy centres coupled to graphene 

      Brenneis, Andreas; Gaudreau, Louis; Seifert, Max; Karl, Helmut; Brandt, Martin S.; Huebl, Hans; Garrido, Jose A; Koppens, Frank H. L.; Holleitner, Alexander W. (Nature Publishin group, 2014-12-01)

      Non-radiative transfer processes are often regarded as loss channels for an optical emitter1 because they are inherently difficult to access experimentally. Recently, it has been shown that emitters, such as fluorophores ...

    • Competing Ultrafast Energy Relaxation Pathways in Photoexcited Graphene
