N2 - Due to its excellent dielectric response, molybdenum disulfide (MoS2) has received more and more attention in the field of optoelectronic materials. In this paper, a terahertz (THz) photoconductive antenna (PCA) based on MoS2 is proposed, and an inter-combined contact tooth design at the antenna gap is nominated. Studies have shown that MoS2 enhances carrier absorption on the semi-insulating gallium arsenide (SI-GaAs) surface, boosting the performance in the frequency range of 0.1-2 THz. The directivity and realized gain of the proposed PCA in overall bandwidth are up to 21.3 dBi and 17 dBi. This paper demonstrates the potential of MoS2 in the field of optoelectronics and provides a new direction for the enhancement of PCA.
