Room-temperature THz detection via EIW effect based on graphite nanosheet
Journal of Infrared and Millimeter Waves(2022)
摘要
We demonstrate a room-temperature sub-terahertz photoconductive detector based on graphite nanosheet(GN)using electromagnetic induced well(EIW)effect produced in the metal-GN-metal structure. The detector achieves high performance of room-temperature THz detection. It shows a responsivity of over 20 kV/W at 0. 035 THz and 11 kV/W at 0. 1673 THz,as well as NEP of about 1. 25 pW/Hz(1/2) at 0. 035 THz and 2. 27 pW/ Hz(1/2) at 0. 1673 THz,respectively. The results open up a new idea for graphene-based THz detection.
