Researchers at the National University of Singapore report a deviation from standard photoresistive behaviors in doped metallic graphene.
Graphene is among these materials, as incident light can excite electrons within it, affecting its electrical conductivity.
The researchers observed that when exposed to continuous-wave terahertz (THz) radiation, Dirac electrons in this material can be thermally decoupled from the lattice, prompting their hydrodynamic transport.
