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…
Anomalous terahertz photoconductivity caused by the superballistic flow of hydrodynamic electrons in graphene
M. Kravtsov, A. L. Shilov, Y. Yang +18
Light incident upon materials can induce changes in their electrical conductivity, a phenomenon referred to as photoresistance. In semiconductors, the photoresistance is negative,…
Fundamental limits of few-layer NbSe microbolometers at terahertz frequencies
K. Shein, E. Zharkova, M. A. Kashchenko +11
The rapid development of infrared spectroscopy, observational astronomy, and scanning near-field microscopy has been enabled by the emergence of sensitive mid- and far-infrared pho…
