Ultrafast, Zero-Bias, Graphene Photodetectors with Polymeric Gate Dielectric on Passive Photonic Waveguides
Vaidotas Mišeikis, Simone Marconi, Marco A. Giambra +15
We report compact, scalable, high-performance, waveguide integrated graphene-based photodetectors (GPDs) for telecom and datacom applications, not affected by dark current. To expl…
Near-unity light absorption in a monolayer WS2 van der Waals heterostructure cavity
Itai Epstein, Bernat Terrés, André J. Chaves +12
Excitons in monolayer transition-metal-dichalcogenides (TMDs) dominate their optical response and exhibit strong light-matter interactions with lifetime-limited emission. While var…
Fast and Sensitive Terahertz Detection Using an Antenna-Integrated Graphene pn Junction
Sebastián Castilla, Bernat Terrés, Marta Autore +11
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 se…
Impact of thermal annealing on graphene devices encapsulated in hexagonal boron nitride
S. Engels, B. Terrés, F. Klein +6
We present a thermal annealing study on single-layer and bilayer (BLG) graphene encapsulated in hexagonal boron nitride. The samples are characterized by electron transport and Ram…
Spatial control of laser-induced doping profiles in graphene on hexagonal boron nitride
Christoph Neumann, Leo Rizzi, Sven Reichardt +6
We present a method to create and erase spatially resolved doping profiles in graphene-hexagonal boron nitride (hBN) heterostructures. The technique is based on photo-induced dopin…
Low B Field Magneto-Phonon Resonances in Single-Layer and Bilayer Graphene
Christoph Neumann, Sven Reichardt, Marc Drögeler +6
Many-body effects resulting from strong electron-electron and electron-phonon interactions play a significant role in graphene physics. We report on their manifestation in low B fi…
