Electrical Spectroscopy of Polaritonic Nanoresonators
Sebastián Castilla, Hitesh Agarwal, Ioannis Vangelidis +13
One of the most captivating properties of polaritons is their capacity to confine light at the nanoscale. This confinement is even more extreme in two-dimensional (2D) materials. 2…
Plasmonic antenna coupling to hyperbolic phonon-polaritons for sensitive and fast mid-infrared photodetection with graphene
Sebastián Castilla, Ioannis Vangelidis, Varun-Varma Pusapati +13
Integrating and manipulating the nano-optoelectronic properties of Van der Waals heterostructures can enable unprecedented platforms for photodetection and sensing. The main challe…
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…
Non-equilibrium properties of graphene probed by superconducting tunnel spectroscopy
Simon Zihlmann, Péter Makk, Sebastián Castilla +6
We report on non-equilibrium properties of graphene probed by superconducting tunnel spectroscopy. A hexagonal boron nitride (hBN) tunnel barrier in combination with a superconduct…
