Abstract: Molybdenum disulphide (MoS2) is a semiconducting transition metal dichalcogenide material which has attracted promising attention in last few years. 2D MoS2 thin films have distinct properties like existence of bandgap that make it more appealing for various applications. Here, we have deposited carbon monoxide (CO) gas sensor based on MoS2 film with nanoworm like surface morphology using DC sputtering technique. Surface morphology and structural characterization of MoS2 film was fully examined by X-ray diffraction, field emission scanning electron microscopy and atomic force microscopy. Performance of MoS2 gas sensor was measured in low detection range (5-1000 ppm) of CO at 200°C. Response of 9.7% was detected for 5 ppm CO at 200°C. The stability of MoS2 gas sensor was also checked for 60 days. Therefore, our results on this nanoworms structured MoS2 gas sensor indicates that this sensor can be utilized for highly stable CO gas sensing application. © 2019 Author(s).
