Tantalum disulfide as Room Temperature Operable Efficient Humidity Sensor

In this present research work, humidity sensing performance of transition metal dichalcogenide, tantalum disulfide (TaS2) was studied. TaS 2 was characterized by XRD and SEM techniques. For the humidity sensing studies, TaS 2 in the pellet form was subjected to humidity sensing studies. Sensing performance of the 2D material TaS 2 was found to be 88% with a quick response and recovery time of 49 and 75 s respectively. It also exhibited a good real sensitivity, limit of detection (LOD), linearity, hysteresis also with a stable sensing stability recorded over a period of two months.
