Tunneling characteristics of twisted double bilayer graphene heterostructures
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +5
Electron tunneling between sheets of bilayer Bernal graphene twisted at different small angles was studied experimentally and theoretically. The current-voltage characteristics exh…
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…
Probing the features of electron dispersion by tunneling between slightly twisted bilayer graphene sheets
Alexey A. Sokolik, Azat F. Aminov, Evgenii E. Vdovin +6
Tunneling conductance between two bilayer graphene (BLG) sheets separated by 2 nm-thick insulating barrier was measured in two devices with the twist angles between BLGs less than…
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…
Inverse Design of Broadband Antennas for Terahertz Devices Based on 2D Materials
M. Lukianov, A. Maevskiy, N. Kazeev +5
Terahertz (THz) technology, a cornerstone of next-generation high-speed communication and sensing, has long been hindered by impedance mismatch challenges that limit device perform…
Limiting performance of graphene bilayer sub-terahertz detectors at large induced band gap
Elena I. Titova, Mikhail A. Kashchenko, Andrey V. Miakonkikh +8
Electrically induced junctions in graphene bilayer (GBL) have shown superior performance for detection of sub-THz radiation at cryogenic temperatures, especially upon electri…
Hysteresis-controlled Van der Waals tunneling infrared detector enabled by selective layer heating
Dmitry A. Mylnikov, Mikhail A. Kashchenko, Ilya V. Safonov +4
Mid-infrared (mid-IR) photodetectors play a crucial role in various applications, including the development of biomimetic vision systems that emulate neuronal function. However, cu…
