With their special electronic and optical properties, nanomaterials such as graphene and molybdenum sulfide have created excitement among scientists for their potential to revolutionize transistors and circuits.
Research is underway that could vastly increase the efficiency and capabilities of the two-dimensional layered semiconductors used in high-speed, flexible electronic devices. But graphene’s structure lacks a feature called a band gap, which allows current through the material to be turned on and off. Unlike graphene, molybdenum sulfide has a band gap and can function as an atomically thin semiconductor and allow atomically thin transistors with high on-off ratios and high voltage gain...
