| In this talk Dr. Castellanos-Gómez will introduce and motivate the study on the fabrication and characterization of the mechanical and electrical properties of atomically thin crystals different than graphene. He will focus on Molibdenum Disulphide which is considered a case of special interest. Single-layer MoS2 is an attractive two-dimensional material that combines the mechanical flexibility of graphene with a large direct bandgap. While graphene is very interesting as a transparent electrode, its lack of a bandgap limits its usefulness in semiconducting and optoelectronic devices. Atomically thin MoS2, on the other hand, has a large intrinsic bandgap. This attractive feature has been recently employed to fabricate many devices not possible in graphene, such as field-effect transistors with high mobility and current on/off ratio, logic gates and efficient photo-transistors. | |
