제목 | A High response photodetector with ALD SnS2 and Graphene hetero-structure |
초록 | Graphene and other two-dimensional materials, such as transition metal dichalcogenides, have rapidly established themselves as intriguing building blocks for optoelectronic applications. Especially, graphene is a promising candidate material for ultra-broadband photodetectors, as its absorption spectrum covers the entire ultraviolet to far-infrared range. However, the responsivity of graphene-based photodetectors has so far been limited due to the small optical absorption of a monolayer of carbon atoms. Here, we demonstrated a highly responsive photodetector based on ALD SnS2-graphene hetero-structure. SnS2 were deposited by atomic layer deposition and SnS2-graphene hybrid photodetectors were fabricated. The properties of photodetector were investigated by XRD, Raman, UPS and electrical characteristics were analyzed. |
