Dual Origin of Room Temperature Sub-Terahertz Photoresponse in Graphene Field Effect Transistors
D. A. Bandurin, I. Gayduchencko, Y. Cao +6
Graphene is considered as a promising platform for detectors of high-frequency radiation up to the terahertz (THz) range due to graphenes superior electron mobility. Previously…
High-temperature quantum oscillations caused by recurring Bloch states in graphene superlattices
R. Krishna Kumar, X. Chen, G. H. Auton +13
Cyclotron motion of charge carriers in metals and semiconductors leads to Landau quantization and magneto-oscillatory behavior in their properties. Cryogenic temperatures are usual…
Superballistic flow of viscous electron fluid through graphene constrictions
R. Krishna Kumar, D. A. Bandurin, F. M. D. Pellegrino +13
Electron-electron (e-e) collisions can impact transport in a variety of surprising and sometimes counterintuitive ways. Despite strong interest, experiments on the subject proved c…
