Abstract :
Photoconductive switches have been extensively studied in time domain spectroscopy (TDS) as THz sources/ detectors. The commonly used devices consist of metal-semiconductor-metal (MSM) structure where Gallium Arsenide (GaAs) is the active layer. In this work, an approach consisting of using semiconducting single-walled carbon nanotubes (s-SWCNTs) instead is proposed. The pristine results showing the photo-response of CNT is presented to illustrate our purpose.
