基于石墨纳米材料的电磁诱导势阱效应的室温太赫兹探测研究
Room-temperature THz detection via EIW effect based on graphite nanosheet
摘要
Abstract
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/Hz1/2 at 0. 035 THz and 2. 27 pW/Hz1/2 at 0. 1673 THz,respectively. The results open up a new idea for graphene-based THz detection.关键词
