Mid-infrared pyro-resistive graphene detector on LiNbO3
Kavitha K. Gopalan, Davide Janner, Sebastien Nanot +4
Mid-infrared (mid-IR) photo-detection has been recently growing in importance because of its multiple applications, including vibrational spectroscopy and thermal imaging. We propo…
Super-Planckian electron cooling in a van der Waals stack
Alessandro Principi, Mark B. Lundeberg, Niels C. H. Hesp +3
Radiative heat transfer (RHT) between macroscopic bodies at separations that are much smaller than the thermal wavelength is ruled by evanescent electromagnetic modes and can be or…
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…
