Electronic properties of two-dimensional MoS$_{\mathrm{2}}$ and its nanoribbons: a theoretical study

Recent advances in producing monolayer and bilayer molybdenum disulfide (MoS$_{\mathrm{2}})$ have generated considerable interest in its fundamental properties. Two-dimensional MoS$_{\mathrm{2}}$ has a variety of intriguing but unexplored electronic and optical properties that are dependent on the number of layers in the material. Here, we present calculations of the electronic properties of two-dimensional MoS$_{\mathrm{2}}$ and its nanoribbons based on a semi-empirical tight-binding model and ballistic quantum transport theory. Utilizing simulation results, we discuss the potential of two-dimensional MoS$_{\mathrm{2}}$ and its nanostructures for low-power electronic applications.
