Abstract

In this paper, we report on the design and fabrication of zinc oxide (ZnO) photoconductive antenna for a terahertz (THz) pulse emitter and detector, and its integration with scanning near-field optical microscopy probe. The fabricated ZnO photoconductive antennas are evaluated in a THz time-domain spectroscopy measurement system. The resistivity of ZnO deposited by rf sputter at the room temperature was 9.6×104 Ω.cm. The bandwidth of ZnO photoconductive antenna was up to 1 THz.
