【摘要】 制备了金属-碲烯-金属的太赫兹光电探测器，实现了毫米波-太赫兹波下的光探测。结果表明，基于对数天线碲烯的太赫兹光电探测器在零偏压下具有较高的光响应率（40 mA/W,0.12 THz），响应时间为8μs，噪声等效功率（NEP）为4 pW·Hz-0.5。研究结果为高性能室温太赫兹光探测提供了一种新的发展路径。更多还原

【Abstract】 A metal-tellurene-metal terahertz photodetector,and realized optical detection under millimeter wave-terahertz wave are fabricated. The results show that the terahertz photodetector based on logarithmic antenna tellurene has a high optical responsivity(40 mA/W,0. 12 THz)under zero bias,a response time of 8 μs,and a noise equivalent power(NEP)of 4 pW·Hz-0. 5. This research results provide a new development path for high-performance room temperature terahertz optical detection.更多还原
