The 2DCC research priorities are organized by four science drivers that are motivated by the unique properties of layered materials that often emerge in ultrathin or few-layer films, necessitating atomic-level control of film growth mode, stoichiometry, point defects and structural imperfections.
|Physics of 2D Systems – provide enabling materials synthesis, characterization, and modeling capabilities to facilitate fundamental studies of new fundamental physical processes that occur in 2D systems, such as efficient spin-charge conversion and the quantum anomalous Hall effect in topological insulators, valleytronics in transition metal dichalcogenides, and quantum transport in 2D heterostructures.|
|Epitaxy of 2D Chalcogenides – understand fundamental mechanisms of 2D film formation in van der Waals bonded systems including the role of the substrate in nucleation and epitaxy, self-limited growth of monolayers, epitaxy in 2D heterostructures, miscibility and alloy formation, intentional doping, and native defects.|
|Next-generation 2D Electronics – provide enabling materials synthesis and characterization capabilities to facilitate development of next-generation electronics (i.e. 2D tunnel transistors, flexible devices, etc.) and quantum information technologies (i.e. single photon sources, spintronics, etc.) as well as associated processing technology (contacts, etching, dielectrics, both optical and electron beam lithography).|
|Advanced Characterization and Modelling – develop techniques and tools to both probe and model 2D chalcogenide films in situ to study the evolution of surface morphology, lateral and vertical domain growth, growth-related defects and grain boundaries, electronic band structure, carrier transport, closely integrated with theory and simulation that targets key kinetic processes during growth, enables new insights on in situ characterization, and accelerates the process of identifying compelling synthetic targets and overcoming experimental obstacles to their synthesis.|
