Detection of High Energy Ionizing Radiation using Deeply Depleted Graphene-Oxide-Semiconductor Junctions
Isaac Ruiz, Gyorgy Vizkelethy, Anthony E. McDonald +4
Graphene's linear bandstructure and two-dimensional density of states provide an implicit advantage for sensing charge. Here, these advantages are leveraged in a deeply depleted gr…
Relative efficiency of polariton emission in two-dimensional materials
Siyuan Dai, Qiong Ma, Yafang Yang +15
We investigated emission and propagation of polaritons in a two dimensional van der Waals material hexagonal boron nitride (hBN). Our specific emphasis in this work is on hyperboli…
Dynamic Wavelength-Tunable Photodetector Using Subwavelength Graphene Field-Effect Transistors
François Léonard, Catalin D. Spataru, Michael Goldflam +2
Dynamic wavelength tunability has long been the holy grail of photodetector technology. Because of its atomic thickness and unique properties, graphene opens up new paradigms to re…
Graphene-Based Platform for Infrared Near-Field Nanospectroscopy of Water and Biological Materials in an Aqueous Environment
Omar Khatib, Joshua D. Wood, Alexander S. McLeod +12
Scattering scanning near-field optical microscopy (s-SNOM) has emerged as a powerful nanoscale spectroscopic tool capable of characterizing individual biomacromolecules and molecul…
Phase transition in bulk single crystals and thin films of VO2 by nano-infrared spectroscopy and imaging
Mengkun Liu, Aaron J. Sternbach, Martin Wagner +21
We have systematically studied a variety of vanadium dioxide (VO2) crystalline forms, including bulk single crystals and oriented thin films, using infrared (IR) near-field spectro…
Ultrafast and Nanoscale Plasmonic Phenomena in Exfoliated Graphene Revealed by Infrared Pump-Probe Nanoscopy
Martin Wagner, Zhe Fei, Alexander S. McLeod +14
Pump-probe spectroscopy is central for exploring ultrafast dynamics of fundamental excitations, collective modes and energy transfer processes. Typically carried out using conventi…
