Abstract A selective room-temperature ammonia sensor using WS 2 nanoflakes as the sensing materials was successfully developed in this work. The two-dimensional WS 2 sharing the same structure with MoS 2 , has a typical graphene-like 2D microstructure. The WS 2 nanoflakes based sensor shows a good sensitivity and an excellent selectivity to ammonia at room temperature. The sensor showed an increased resistance when exposed to ammonia from 1 ppm to 10 ppm indicating a p-type response. The… CONTINUE READING
