Summary:

The fascinating properties of graphene which sparked an interest in 2D materials has led to the discovery of other 2D crystals such as boron nitride (BN), molybdenum disulfide (MoS2), and tungsten disulfide (WS2). These materials often possess properties that are strong in areas where graphene is weaker; for example, the 2-dimensional form of the transition metal dichalcogenides MoS2 and WS2 each possess a direct bandgap and have high levels of photoluminescence. Moreover, they can be gated by external electric field. This makes them ideal for making FETs with high ON/OFF ratio. These properties can allow for the creation of low-power transistors and optoelectronic devices. In this talk, I will overview the significance of being able to make these materials by CVD and other methods, the advantageous properties and application areas of select 2D materials, as well as how they complement graphene’s extraordinary properties.
