Giant Surface Plasmon Induced Drag Effect (SPIDEr) in Metal Nanowires

摘要

Here, for the first time we predict a giant surface plasmon-induced drag effect (SPIDEr), which exists under conditions of the extreme nanoplasmonic confinement. Under realistic conditions, in nanowires, this giant SPIDEr generates rectified THz potential differences up to 10 V and extremely strong electric fields up to ～ 10~5 - 10~6 V/cm. The SPIDEr is an ultrafast effect whose bandwidth for nanometric wires is ～ 20 THz. The giant SPIDEr opens up a new field of ultraintense THz nanooptics with wide potential applications in nanotechnology and nanoscience, including microelectronics, nanoplasmonics, and biomedicine.
