Electrical Control of Linear Dichroism in Black Phosphorus from the Visible to Mid-Infrared
Michelle C. Sherrott, William S. Whitney, Deep Jariwala +4
The incorporation of electrically tunable materials into photonic structures such as waveguides and metasurfaces enables dynamic control of light propagation by an applied potentia…
High Photovoltaic Quantum Efficiency in Ultrathin van der Waals Heterostructures
Joeson Wong, Deep Jariwala, Giulia Tagliabue +4
We report experimental measurements for ultrathin (< 15 nm) van der Waals heterostructures exhibiting external quantum efficiencies exceeding 50%, and show that these structures ca…
Atomic-scale Structural and Chemical Characterization of Hexagonal Boron Nitride Layers Synthesized at the Wafer-Scale with Monolayer Thickness Control
Wei-Hsiang Lin, Victor W. Brar, Deep Jariwala +5
Hexagonal boron nitride (h-BN) is a promising two-dimensional insulator with a large band gap and low density of charged impurities that is isostructural and isoelectronic with gra…
Experimental Demonstration of >230° Phase Modulation in Gate-Tunable Graphene-Gold Reconfigurable Mid-Infrared Metasurfaces
Michelle C. Sherrott, Philip W. C. Hon, Katherine T. Fountaine +5
Metasurfaces offer significant potential to control far-field light propagation through the engineering of amplitude, polarization, and phase at an interface. We report here phase…
Field Effect Optoelectronic Modulation of Quantum-Confined Carriers in Black Phosphorus
William S. Whitney, Michelle C. Sherrott, Deep Jariwala +4
We report measurements of the infrared optical response of thin black phosphorus under field-effect modulation. We interpret the observed spectral changes as a combination of an am…
Near Unity Absorption in Van der Waals Semiconductors for Ultrathin Optoelectronics
Deep Jariwala, Artur R. Davoyan, Giulia Tagliabue +3
We demonstrate near unity, broadband absorbing optoelectronic devices using sub-15 nm thick transition metal dichalcogenides (TMDCs) of molybdenum and tungsten as van der Waals sem…
Electronic modulation of infrared emissivity in graphene plasmonic resonators
Victor W. Brar, Michelle C. Sherrott, Luke A. Sweatlock +4
Electronic control of blackbody emission from graphene plasmonic resonators on a silicon nitride substrate is demonstrated at temperatures up to 250 C. It is shown that the graphen…
Tunable Large Resonant Absorption in a Mid-IR Graphene Salisbury Screen
Min Seok Jang, Victor W. Brar, Michelle C. Sherrott +5
Enhancing the interaction strength between graphene and light is an important objective for those seeking to make graphene a relevant material for future optoelectronic application…
