Flexible Large MoS 2 Film Based Ammonia Sensor

This paper describes the fabrication of a cost-effective, low-power flexible ammonia sensor that uses few layered molybdenum disulphide (MoS2) nanoflakes as the sensing layer. The nanoflakes were exfoliated using a sonicationassisted liquid exfoliation approach. A thin film of MoS2 was spin coated on a polymethyl methacrylate film, and aluminium electrodes were deposited on the top of the film tha...
