Abstract
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. MoS2 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 MoS2 leads to a substantial increase in the photoresponsivity ([Formula: see text] of the MoS2@MWCNTs hybrid compared to bare MoS2 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 MoS2.
