Project Title: Theory Design of Charged Defects for Two-dimensional Quantum Technologies

Project summary: The central motivation for this research is to make it possible to conduct first-principles design of charged defects in monolayer two-dimensional (2D) materials and their heterojunctions for quantum technologies.  Defects in 2D materials such as h-BN have recently been found to be promising single-photon emitters with polarized and ultrabright single-photon emission at room temperature. This indicates the unprecedented potential of 2D materials for large-scale nanophotonics and quantum information processing.  The proposed project will develop new computational techniques to accurately predict charged defects’ ground state and excited state properties in ultrathin 2D materials and heterojunctions, making it possible to design complex defects with ideal properties for quantum applications such as quantum emitters and quantum computing.
