Heteroatom quantum corrals and nanoplasmonics in graphene (HeQeCoG)

2015–2018

The objective of this project is to create atomically precise structures made of silicon and phosphorus atoms embedded in the lattice of graphene. This will be achieved by combining proven modeling techniques with sample fabrication via carefully controlled ion implantation, and subsequent manipulation in an atomic resolution scanning transmission electron microscope (STEM).

The structures will be computationally designed for interesting nanoplasmonic enhancement and quantum confinement properties, and characterized by electron energy loss spectroscopy mapping in the STEM. The expected outcome is a demonstration of the feasibility of atomic-level material design and the creation of freestanding “quantum corral” structures for the first time.
