摘要

在本文中，我们提出了一种由多壁碳纳米管(MWCNTs)和二硫化钼(MoS)组成的新型杂化材料，该材料在近红外(NIR)区域具有增强的光响应性。在NMP溶剂中通过化学剥离得到MoS 2纳米片，并使用化学气相沉积(CVD)技术在这些纳米片上生长MWCNTs。MWCNTs的近红外透明度与MoS 2的高紫外光吸收相结合，导致MoS 2 @MWCNTs杂化物的光响应率([公式:见文])在近红外区域与裸MoS 2相比显著增加。实验结果表明，在杂化材料中[公式:见文]的a /W从18.6[公式:见文]提高到155.7[公式:见文]，而在裸MoS 2的情况下观察到相反的趋势。

Enhancing near-infrared photoresponsivity in mos-based photodetectors through mwcnts integration

In this paper, we present a novel hybrid material consisting of multiwalled carbon nanotubes (MWCNTs) and molybdenum disulfide (MoS[Formula: see text] with enhanced photoresponsivity in the near-infrared (NIR) region. MoS 2 nanosheets are obtained through chemical exfoliation in NMP solvent, and MWCNTs are grown on these nanosheets using the chemical vapor deposition (CVD) technique. The combination of the NIR transparency of MWCNTs and the high UV light absorption of MoS 2 leads to a substantial increase in the photoresponsivity ([Formula: see text] of the MoS 2 @MWCNTs hybrid compared to bare MoS 2 specifically in the NIR region. Experimental results demonstrate a remarkable enhancement of [Formula: see text] from 18.6 [Formula: see text]A/W to 155.7 [Formula: see text]A/W in the hybrid material, whereas the opposite trend is observed in the case of bare MoS 2 .
