First practical application of viscous electron flow realizes terahertz photoconductivity in graphene
"in doped metallic graphene Dirac electrons exposed to continuous-wave THz photoresistance is thermally decoupled from the lattice activating hydrodynamic electron transport... in this regime, the resistance of graphene constrictions experiences a decrease caused by the THz-driven superballistic flow of correlated electrons... superballistic devices as sensitive phonon-cooled bolometers offering ps-scale response time... ultra-fast THz sensors, electron thermometers"
