Abstract

Recent studies using Laser THz Emission Nanoscopy have shown that a single gold nanorod was able to modify the emission from an InAs surface although the nanorod was not resonant with the incident laser pulses. Here, we present our studies on THz emission spectroscopy on gold nanorods with different geometrical orientations i.e. standing versus lying on an InAs surface. We show that gold nanorods resonant with the incident femtosecond laser gives an enhanced THz emission from the InAs surface, while the separation distance between each individual nanorod also plays a significant role.
