This review highlights recent and novel trends focused on metallic (plasmonic) and dielectric
metasurfaces in photoconductive terahertz (THz) devices. We demonstrate the great …

This study proposes a new-fashioned plasmonic photoconductive antenna (PCA) with high
optical-to-terahertz (THz) conversion efficiency. Finite element method was used to …

A new design for an unbiased antennaless terahertz (THz) photoconductive antenna (PCA)
using an array of bimetallic nanostructures located underneath the low temperature gallium …

By virtue of the surface plasmon resonance effect, plasmonic nanoparticles (NPs) can
localize the light field and significantly enhance the performance of some optoelectronic …

One major problem of the conventional solar cells is low conversion efficiency. In this work,
we have proposed a new design including hemisphere texturing on top and metallic …

In this thesis, we have first introduced a new setup for the reliable characterization of
photoconductive antennas to be used in THz time-domain spectroscopy. Using this setup …
