세미나 제목 : Optoelectronics & Electronics based on 2D Semiconductor Heterostructures

발표초록 : Two-dimensional (2D) van der Waals (vdW) heterostructures built from various atomic layered materials provide an unprecedented opportunity in designing new material systems owing to ability to create high-quality heterointerfaces between non-commensurate lattices. The recent advent of semiconducting transition metal dichalcogenides (TMDCs) with excellent electrical and optical properties, combined with the ability to build artificial heterostructures, allows the realization of atomically thin semiconductor heterostructures for novel device applications as well as fundamental studies in an ultimate thickness limit. In this talk, I will present the fabrication and electrical and optoelectronic properties of various vdW heterostructures including atomically thin p-n junctions and 2D semiconductor/oxide heterojunctions. Furthermore, I will discuss the large-area growth of high-quality monolayer TMDCs using metal-organic chemical vapor deposition (MOCVD) for future practical applications.
