| 제목 | Diverse electronic sensors based on 2D Nanomaterials |
| 초록 | Diverse 2D layered nanomaterials such as graphene, boron nitride, mxene, metal hydroxide, and transition metal dichalcogenides (TMDs) have attracted much attention as promising materials for chemical and optical sensing devices. Among them, 2D TMDs have lots of merits for sensing applications. First, we will discuss a couple of considerations of 2D nanomaterials required for practical chemical sensor applications in terms of strategies such as electronic sensitization through metal decoration, lattice doping, and surface area increase. We will also suggest unique 2D heterostructure designs combined with the graphene or 2D metallic TMD. Secondly, we will introduce a 2D TMDs synthesis with low-temperature, high-throughput, and large-area capability and the corresponding photonic applications. In order to achieve this goal, we successfully developed an atmospheric-pressure plasma-enhanced chemical vapor deposition (AP-PECVD) technique or in-situ plasma sulfurization process. The as-fabricated MoS2/Si and WS2/Si heterojunctions exhibited large and fast photocurrent responses under light illumination. All the results demonstrated that our simple 2D synthesis methods could produce 2D heterojunction based photodiode for optoelectronic applications. These studies would help us pave a way toward futuristic gas and optical sensing platforms based on diverse 2D materials. |
