A black phosphorus photo-detector for multispectral, high-resolution imaging
Michael Engel, Mathias Steiner, Phaedon Avouris
Black phosphorus is a layered semiconductor that is intensely researched in view of applications in optoelectronics. In this Letter, we investigate a multi-layer black phosphorus p…
Substrate Sensitive Mid-Infrared Photoresponse in Graphene
Marcus Freitag, Tony Low, Luis Martin-Moreno +3
We report mid-infrared photocurrent spectra of graphene nanoribbon arrays on SiO2 dielectrics showing dual signatures of the substrate interaction. First, hybrid polaritonic modes…
Plasmons and screening in monolayer and multilayer black phosphorus
Tony Low, Rafael Roldán, Han Wang +4
Black phosphorus exhibits a high degree of band anisotropy. However, we found that its in-plane static screening remains relatively isotropic for momenta relevant to elastic long-r…
Graphene Plasmonics for Terahertz to Mid-Infrared Applications
Tony Low, Phaedon Avouris
In recent years, we have seen a rapid progress in the field of graphene plasmonics, motivated by graphene's unique electrical and optical properties, tunabilty, long-lived collecti…
