"Paper and Circuits, only Atoms Thick"
2D layered materials are like papers: they can be colored, stitched, stacked, and folded to form integrated devices with atomic thickness. In this talk, I will discuss how di erent 2D materials can be grown with distinct electrical and optical properties (col- oring), how they can be connected laterally to form pattered circuits (stitching), and how their properties can be controlled by the interlayer rotation (twisting). We will then discuss how these atomically thin papers and circuits can be folded to generate active 3D systems.
One of Professor Park's main research goals is to build atomically-thin integrated circuitry. In order to build atomically thin integrated circuitry, his group develops advanced growth, characterization and device fabrication methods for2D layered materials, which include electrically conducting graphene, insulating hBN and semiconducting transition metal dichalcogenides. Another research goal is to explore novel electrical, optical, and optoelectronic properties of low-dimensional nanostructures, which will allow the development of advanced devices, including highly efficient solar cells, ultrasensitive infrared bolometric detectors, and novel valleytronic and spintronic devices.
