Electronic bistability, discontinuous switching and stochasticity in a two-dimensional semiconductor
S. Jana, M. Kravtsov, A. Ermakov +11
Bistability - two stable electronic states under the same bias - underlies switching and memory, but is usually absent in transistors and must be engineered through material means:…
Correlated Insulator Moiré Bolometer
L. Elesin, A. L. Shilov, M. Kravtsov +14
Light incident on an insulator is generally not expected to turn it into a metal without invoking intense ultrafast excitation that leads to transient structural transitions. Here…
Near-unity efficiency optical vortex generation in van der Waals materials
Sujeong Byun, Munseong Bae, Hangsung Cho +4
Optical spin-orbit coupling provides a promising, fabrication-free route for developing ultra-compact optical vortex generators. However, the conversion efficiency has been theoret…
Broadband dielectric permittivity tensor of muscovite for next-generation all van der Waals photonic components
Meri Hayrapetyan, Maksim Sargsyan, David Karakhanyan +8
We report a comprehensive determination of the broadband dielectric permittivity tensor of van der Waals (vdW) muscovite also referred to as mica, establishing it as a low-index lo…
Polymer-free van der Waals assembly of 2D material heterostructures using muscovite crystals
Ian Babich, Timofey M. Savilov, Natalia A. Mamchik +14
The advent of van der Waals (vdW) heterostructures has enabled formation of bespoke materials with atomic precision, where numerous quantum and topological phenomena have already b…
Gate-Tunable Photoresponse of Graphene Josephson Junctions at Terahertz Frequencies
X. Zhou, I. Gayduchenko, A. Kudriashov +12
Graphene Josephson junctions (JJ) provide a promising platform for ultra-broadband quantum sensing of light owing to graphene's frequency-independent absorption, vanishing electron…
