Improved gas sensing capabilities of MoS2/diamond heterostructures at room temperature
Original language description
MoS2 and NCD have attracted considerable attention due to their unique electronic structure and extraordinary physical and chemical properties in many applications. In this study, the synthesis of MoS2 and H-NCD thin films using appropriate physical/chemical deposition methods and their analysis in terms of gas sensing properties in their individual and combined forms are demonstrated. The sensitivity and time domain characteristics of the sensors were investigated for three gases: NO2, NH3 and neutral synthetic air. It was observed that the heterostructure-based gas sensor exhibits improved sensitivity to oxidizing NO2 and reducing NH3 gases compared to pure active materials. Different gas interaction model pathways were developed to describe the current flow mechanism through the sensing area with/without heterostructure. The gas interaction model independently considers the influence of each material as well as the current flow mechanism through the formed P-N heterojunction.
