Phonon-mediated mid-infrared photoresponse of graphene
Michela Badioli, Achim Woessner, Klaas-Jan Tielrooij +5
The photoresponse of graphene at mid-infrared frequencies is of high technological interest and is governed by fundamentally different underlying physics than the photoresponse at…
Thermoelectric detection of propagating plasmons in graphene
Mark B. Lundeberg, Yuanda Gao, Achim Woessner +7
Controlling, detecting and generating propagating plasmons by all-electrical means is at the heart of on-chip nano-optical processing. Graphene carries long-lived plasmons that are…
Ultra-confined acoustic THz graphene plasmons revealed by photocurrent nanoscopy
Pablo Alonso-Gonzalez, Alexey Y. Nikitin, Yuanda Gao +14
Terahertz (THz) fields are widely applied for sensing, communication and quality control. In future applications, they could be efficiently confined, enhanced and manipulated - wel…
