In this work, we report on the vapor-based synthesis of molybdenum disulphide (MoS 2 ), which is one of the most widely studied two-dimensional (2D) layered materials since the large body of work conducted on the quintessential layered material, graphene. In addition, we have fabricated and characterized a MoS 2 photodetector which was formed using a visco-elastic stamping technique. This device exhibits a low Schottky barrier height of ∼27 meV and a photoresponsivity of 1,314 A/W at room temperature using a broad band light source with irradiance power of 0.134 nW at 5 V drain-source voltage. Our results show the promise of MoS 2 for photodetectors and a range of other applications.
