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…
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…
Graphene Zero-Bias Sub-Terahertz Turnkey Detector with Above 43 GHz Bandwidth
E. I. Titova, A. Titchenko, M. Titova +16
High-frequency terahertz (THz) detectors are vital for next-generation high-speed wireless communication systems. Graphene, with its high carrier mobility, broadband absorption, an…
Enhanced Terahertz Thermoelectricity via Engineered van Hove Singularities and Nernst Effect in Moiré Superlattices
L. Elesin, A. L. Shilov, S. Jana +14
Thermoelectric materials, long explored for energy harvesting and thermal sensing, convert heat directly into electrical signals. Extending their application to the terahertz (THz)…
Reconstructing Critical Current Density in Josephson Junctions with Phase Non-linearity
A. Kudriashov, R. A. Hovhannisyan, X. Zhou +4
In this Letter, we show that the standard Dynes-Fulton analysis, commonly used to reconstruct the critical current density from interference patterns, breaks down in Josephson junc…
