Nonlinear plasmonic response in GaAs/InGaAs core/shell nanowires.

We show nonlinear plasmonic response in GaAs/In0.2Ga0.8As nanowires using high field terahertz pulses. With increasing THz field, plasmon resonance is redshifted, and spectral weight decreases indicating an inhomogeneous intervalley electron scattering across the nanowire.

Keywords: Intense Terahertz pulses; Nanowires; Plasmon
