| contents | Transition metal dichalcogenides have shown great promise in the field of gas sensing due to their high catalytic activity and unique electronic properties. They can effectively interact with various gas molecules, making them suitable materials for high performance gas sensors. In this work, we have studied the sensing properties of nitrogen containing gases on different heterostructures using density functional studies. The result shows that NH3 and NOx exhibit weak electronic interactions with MoS/WTe and MoTe/WS heterostructures and strong electronic interactions are observed between NH3 and NOx molecules with MoS/IrO and MoS/TiO heterostructures. |
