Abstract

This work presents the growth, fabrication and characterization of low-temperature-grown gallium arenide as a prototype for terahertz photoconductive antenna detector. The grown film was used as a substrate for a 10μm-gap bow-tie photoconductive antenna structure fabricated using standard ultraviolet photolithography and electron beam deposition techniques. Terahertz time-domain spectroscopy was utilized to evaluate its capability for terahertz detection. Results were compared to a commercial dipole photoconductive antenna.
