    • Fast and sensitive terahertz detection using an antenna-integrated graphene pn-junction 

      Castilla, Sebastián; Terrés, Bernat; Autore, Marta; Viti, Leonardo; Li, Jian; Nikitin, Alexey Y.; Vangelidis, Ioannis; Watanabe, Kenji; Taniguchi, Takashi; Lidorikis, Elefterios; Vitiello, Miriam S.; Hillenbrand, Rainer; Tielrooij, Klaas-Jan; Koppens, Frank H.L. (ACS, 2019-03-18)
      Article
      Open Access
      Although the detection of light at terahertz (THz) frequencies is important for a large range of applications, current detectors typically have several disadvantages in terms of sensitivity, speed, operating temperature, ...
    • Highly confined low-loss plasmons in graphene–boron nitride heterostructures 

      Woessner, Achim; Lundeberg, Mark B.; Gao, Yuanda; Principi, Alessandro; Alonso-González, Pablo; Carrega, Matteo; Watanabe, Kenji; Taniguchi, Takashi; Vignale, Giovanni; Polini, Marco; Hone, James; Hillenbrand, Rainer; Koppens, Frank H.L. (Nature Publishing Group, 2014-12-22)
      Article
      Open Access
      Graphene plasmons were predicted to possess simultaneous ultrastrong field confinement and very low damping, enabling new classes of devices for deep-subwavelength metamaterials, single-photon nonlinearities, extraordinarily ...
    • Nanoscale Imaging and Control of hexagonal BoronNitride Single Photon Emitters by a Resonant Nano-antenna 

      Palombo Blascetta, Nicola; Liebel, Matz; Lu, Xiaobo; Taniguchi, Takashi; Watanabe, Kenji; Efetov, Dmitri K.; Hulst, Niek F. van (American Chemical Society, 2020-02-13)
      Article
      Restricted access - publisher's policy
      Defect centers in two-dimensional hexagonal boron nitride (hBN) are drawing attention as single photon emitters with high photo-stability at room temperature. With their ultra-high photon-stability, hBN single photon ...
    • Thermoelectric detection and imaging of 1 propagating graphene plasmons 

      Lundeberg, Mark B.; Gao, Yuanda; Woessner, Achim; Tan, Cheng; Alonso-González, Pablo; Watanabe, Kenji; Taniguchi, Takashi; Hone, James; Hillenbrand, Rainer; Koppens, Koppens (Nature, 2016-09-19)
      Article
      Open Access
      Controlling, detecting and generating propagating plasmons by all-electrical means is at the heart of on-chip nano-optical processing1, 2, 3. Graphene carries long-lived plasmons that are extremely confined and controllable ...
