  • Generation of photovoltage in graphene on a femtosecond timescale through efficient carrier heating 

    Tielrooij, K. J.; Piatkowski, L.; Massicotte, M.; Woessner, Achim; Ma, Q.; Lee, Y.; Myhro, K. S.; Lau, C. N.; Jarillo-Herrero, P.; Hulst, N. F. van; Koppens, F. H. L. (Nature, 2015-04-13)
    Article
    Open Access
    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 ...
  • Hot-carrier photocurrent effects at graphene–metal interfaces 

    Tielrooij, K. J.; Massicotte, M.; Piatkowski, L.; Woessner, Achim; Ma, Q.; Jarillo-Herrero, P.; Hulst, N. F. van; Koppens, F. H. L. (IOP, 2015-03-02)
    Article
    Open Access
    Photoexcitation of graphene leads to an interesting sequence of phenomena, some of which can be exploited in optoelectronic devices based on graphene. In particular, the efficient and ultrafast generation of an electron ...
  • Real-space mapping of tailored sheet and edge plasmons in graphene nanoresonators 

    Nikitin, A. Y.; Alonso-González, P.; Vélez, S.; Mastel, S.; Centeno, A.; Pesquera, A.; Zurutuza, A.; Casanova, F.; Hueso, L. E.; Koppens, F. H. L.; Hillenbrand, R. (2016-03-21)
    Article
    Open Access
    Plasmons in graphene nanoresonators have many potential applications in photonics and optoelectronics, including room-temperature infrared and terahertz photodetectors, sensors, reflect arrays or modulators1, 2, 3, 4, 5, ...
