Giant surface-plasmon-induced drag effect in metal nanowires

Here, for the first time we predict a giant surface-plasmon-induced drag-effect rectification (SPIDER), which exists under conditions of the extreme nanoplasmonic confinement. In nanowires, this giant SPIDER generates rectified THz potential differences up to 10V and extremely strong electric fields up to ∼105-106V/cm. The giant SPIDER is an ultrafast effect whose bandwidth for nanometric wires is ∼20THz. It opens up a new field of ultraintense THz nanooptics with wide potential applications in nanotechnology and nanoscience, including microelectronics, nanoplasmonics, and biomedicine.
