Beam steering at the nanosecond time scale with an atomically thin reflector
Trond I. Andersen, Ryan J. Gelly, Giovanni Scuri +15
Techniques to mold the flow of light on subwavelength scales enable fundamentally new optical systems and device applications. The realization of programmable, active optical syste…
Electrically controlled emission from singlet and triplet exciton species in atomically thin light emitting diodes
Andrew Y. Joe, Luis A. Jauregui, Kateryna Pistunova +15
Excitons are composite bosons that can feature spin singlet and triplet states. In usual semiconductors, without an additional spin-flip mechanism, triplet excitons are extremely i…

Moiré superlattices in twisted van der Waals materials constitute a promising platform for engineering electronic and optical properties. However, a major obstacle to fully underst…
Nanoscale Thermal Imaging of VO via Poole-Frenkel Conduction
Alyson Spitzig, Adam Pivonka, Alex Frenzel +8
We present a method for nanoscale thermal imaging of insulating thin films using atomic force microscopy (AFM), and we demonstrate its utility on VO. We sweep the applied volta…
Temperature-independent thermal radiation
Alireza Shahsafi, Patrick Roney, You Zhou +11
Thermal emission is the process by which all objects at non-zero temperatures emit light, and is well-described by the classic Planck, Kirchhoff, and Stefan-Boltzmann laws. For mos…
Controlling excitons in an atomically thin membrane with a mirror
You Zhou, Giovanni Scuri, Jiho Sung +9
We demonstrate a new approach for dynamically manipulating the optical response of an atomically thin semiconductor, a monolayer of MoSe2, by suspending it over a metallic mirror.…

Luis A. Jauregui, Andrew Y. Joe, Kateryna Pistunova +13
Excitons in semiconductors, bound pairs of excited electrons and holes, can form the basis for new classes of quantum optoelectronic devices. A van der Waals heterostructure built…
Limiting optical diodes enabled by the phase transition of vanadium dioxide
Chenghao Wan, Erik Horak, Jonathan King +8
A limiting optical diode is an asymmetric nonlinear device that is bidirectionally transparent at low power, but becomes opaque when illuminated by sufficiently intense light incid…
Radiative thermal runaway due to negative differential thermal emission across a solid-solid phase transition
David M. Bierman, Andrej Lenert, Mikhail A. Kats +6
Thermal runaway occurs when a rise in system temperature results in heat generation rates exceeding dissipation rates. Here we demonstrate that thermal runaway occurs in thermal ra…
