摘要

近年来，光电探测器得到了广泛的研究。本文将单壁碳纳米管（SWCNTs）与砷化镓材料结合，研究了SWCNTs/石墨烯/砷化镓光电探测器的性能。我们测量了器件在808 nm处的光响应。响应度可达185.16 mA·W−1，探测率为1.42 × 1010 Jones。同时，该器件在10 kHz时具有快速响应，上升/下降时间为4.6 μs/30.8 μs。该结果为SWCNTs/GaAs杂化结构近红外探测器的应用提供了新的途径。

High performance near-infrared photodetector based on single-walled carbon nanotubes and graphene

In recent years, photodetectors have been extensively studied. In this paper, single-walled carbon nanotubes (SWCNTs) were combined with GaAs materials to investigate the performance of SWCNTs/Graphene/GaAs photodetectors. We measured the optical response of the device at 808 nm. The responsivity was up to 185.16 mA·W⁻¹, and the detectivity was 1.42 × 10¹⁰ Jones. Meanwhile, the device possessed a fast response with rise/fall time of 4.6 μs/30.8 μs at 10 kHz. The results provide a new avenue for the application of near-infrared photodetectors with SWCNTs/GaAs hybrid structures.
