    摘要:

    基于石墨纳米材料成功制备金属-石墨-金属结构电磁诱导势阱效应室温太赫兹探测器,实现了高性能的室温太赫兹探测。器件在0.035 THz的响应率达到20 kV/W 在0.1673 THz的响应率达到11 kV/W,器件在0.035 THz的噪声等效功率达到1.25 在0.1673 THz的噪声等效功率达到2.27 。我们的研究结果为石墨烯太赫兹探测器提供新的思路。

    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.
