Symposium FF01—Beyond Graphene 2D Materials—Synthesis, Properties and Device Applications
Inspired by the exotic properties of graphene, the vast interest in “beyond graphene” two-dimensional (2D) and layered materials have been driven by the compelling properties of individual atomic layers compared to their bulk counterparts. Such properties include the emergence of a direct bandgap with large exciton binding energies, valley polarization, magnetism and colossal piezoelectricity, all of which depend on the composition, crystal structure, and number of individual layers. 2D materials are extreme surfaces that exhibit strong in-plane along with weak out-of-plane bonding, and are susceptible to physical, electrical and/or chemical modifications, opening up many avenues for novel applications. Evidently, these 2D materials offer the ultimate flexibility and scaling potential for device miniaturization, as well as a remarkable platform to study new phenomena in chemistry, materials science, biology and condensed matter physics. This interdisciplinary symposium brings together a diverse host of researchers to capture the latest developments in synthesis, properties, characterization and applications of “beyond graphene” 2D materials, with emphasis on elemental (phosphorene, silicene, tellurene, etc.), 2D compounds (MXenes, oxides, nitrides and carbides) and 2D layered (transition-metal di-/tri-chalcogenides, group-III/-IV chalcogenides) materials, alloys and their van der Waals heterostructures. Furthermore, it will focus on recent progress of novel devices enabled by 2D materials, particularly with recent developments in viable routes for large scale synthesis, doping and integration of monolayers, lateral and vertical heterostructures, and the emergence of 2D perovskites and hybrid organic-inorganic 2D heterostructures.
