High-Sensitivity 2D MoS(2)/1D MWCNT Hybrid Dimensional Heterostructure Photodetector

A photodetector based on a hybrid dimensional heterostructure of laterally aligned multiwall carbon nanotubes (MWCNTs) and multilayered MoS(2) was prepared using the micro-nano fixed-point transfer technique. Thanks to the high mobility of carbon nanotubes and the efficient interband absorption of M...

description A photodetector based on a hybrid dimensional heterostructure of laterally aligned multiwall carbon nanotubes (MWCNTs) and multilayered MoS(2) was prepared using the micro-nano fixed-point transfer technique. Thanks to the high mobility of carbon nanotubes and the efficient interband absorption of MoS(2), broadband detection from visible to near-infrared (520–1060 nm) was achieved. The test results demonstrate that the MWCNT-MoS2 heterostructure-based photodetector device exhibits an exceptional responsivity, detectivity, and external quantum efficiency. Specifically, the device demonstrated a responsivity of 3.67 × 10(3) A/W (λ = 520 nm, V(ds) = 1 V) and 718 A/W (λ = 1060 nm, V(ds) = 1 V). Moreover, the detectivity (D*) of the device was found to be 1.2 × 10(10) Jones (λ = 520 nm) and 1.5 × 10(9) Jones (λ = 1060 nm), respectively. The device also demonstrated external quantum efficiency (EQE) values of approximately 8.77 × 10(5)% (λ = 520 nm) and 8.41 × 10(4)% (λ = 1060 nm). This work achieves visible and infrared detection based on mixed-dimensional heterostructures and provides a new option for optoelectronic devices based on low-dimensional materials.
