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:…
Interaction-limited conductivity of twisted bilayer graphene revealed by giant terahertz photoresistance
A. L. Shilov, M. Kravtsov, J. Covey +15
Identifying the microscopic processes that limit conductivity is essential for understanding correlated and quantum-critical states in quantum materials. In twisted bilayer graphen…
Plasmon resonance in a sub-THz graphene-based detector: theory and experiment
I. M. Moiseenko, E. Titova, M. Kashchenko +1
We present a combined experimental and theoretical study of photovoltage generation in a bilayer graphene (BLG) transistor structure exposed to subterahertz radiation. The device f…
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)…
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…
