Like graphene, Molybdenum disulfide (MoS2) is a semiconductor that is gaining popularity due to its reduced dimensionality and large bandgap in nanoscale optoelectronic applications. MoS2 is made up of layers that can be easily separated to obtain few-layer or single-layer samples. When the thickness is reduced to single-layer, MoS2 possesses significant advantages over current materials such as graphene and carbon nanotubes. Such advantages include a direct and non-zero bandgap, making optoelectronic devices in the visible range possible.



Stage of Development 

There are several working prototypes that have been developed. Some of the work has been published in Nature (referenced below).
