摘要

本文研究了表面纳米图案对太赫兹光导天线(PCA)的影响。表面图案有助于定位入射红外激发，从而减少反射。通过在电流路径中引入缺陷态，减少了载流子复合时间。当电场偏置场与光泵偏振平行时，这种组合效应使器件的太赫兹辐射提高了220%。

Enhancing the THz emission through surface patterning in Photo-Conductive Antenna

In this article we have investigated the effect of surface nano-patterns in THz Photo-Conductive Antennae (PCA). The surface patterns help to localize the incident IR excitation thus reduces the reflection. It also reduces carrier recombination time by introducing defect states in current path. The combined effect enhances the THz emission from the device up to 220% when the electrical bias field is parallel to the optical pump polarization.
