like graphene, down to a single monolayer. This elemental 2D semiconductor offers several distinctive_x000D_
features: remarkably high carrier mobilities, an anisotropic band structure, and a direct gap that efficiently_x000D_
absorbs light. In addition, BP offers two characteristics unmatched by any other 2D or bulk materials: a tunable_x000D_
direct bandgap from the mid-infrared to the visible via the sample thickness and the ability to dynamically tune_x000D_
the gap through an applied electric field. These characteristics present unique opportunities for the_x000D_
development of low-cost photodetectors with enhanced responsivities and operating frequencies in the_x000D_
technologically important infrared region of the spectrum. In close partnership with Excelitas, one of the most_x000D_
important photodetector manufacturers in the world, we will develop a number of infrared photodetector_x000D_
architectures based on BP. In particular, we will develop electric-field tunable BP photodetectors to extend the_x000D_
intrinsic spectral range of BP beyond 4 microns, we will enhance their sensitivity by using optical metasurfaces_x000D_
and finally we will develop low-cost large-area BP detectors using solution-based processing of BP_x000D_
nanoparticles. Black phosphorus detectors will have potential applications in telecommunications,_x000D_
spectroscopy, range finding and thermal imaging. Within the context of this Project, we will specifically_x000D_
benchmark BP tunable detectors as potential trace gas sensors., program purpose french : Black phosphorus is a stable allotrope of phosphorus that exhibits a layered structure that can be exfoliated,_x000D_
