Defects and Defect Engineering of Two-Dimensional Transition Metal Dichalcogenide (2D TMDC) Materials.

As layered materials, transition metal dichalcogenides (TMDCs) are promising two-dimensional (2D) materials. Interestingly, the characteristics of these materials are transformed from bulk to monolayer. The atomically thin TMDC materials can be a good alternative to group III-V and graphene because of their emerging tunable electrical, optical, and magnetic properties.

Towards Low-Temperature CVD Synthesis and Characterization of Mono- or Few-Layer Molybdenum Disulfide.

Molybdenum disulfide (MoS) transistors are a promising alternative for the semiconductor industry due to their large on/off current ratio (>10), immunity to short-channel effects, and unique switching characteristics. MoS has drawn considerable interest due to its intriguing electrical, optical, sensing, and catalytic properties. Monolayer MoS is a semiconducting material with a direct band gap of ~1.
