Researchers from the Moscow Institute of Physics and Technology (MIPT) have grown atomically thin films of molybdenum disulfide over much of a 100mm wafers, and built a transistor from the material. Like graphene, molybdenum disulfide can be created in a mono-layer. Unlike graphene, which is a conductor, MoS2 is a semiconductor with a bandgap. “Each ...
