The field of two-dimensional (2D) and layered materials continues to excite many researchers around the world who are eager to advance and innovate viable routes for large scale synthesis, doping and integration of monolayers and the development of unique characterization approaches for studying and harnessing exotic properties that could help enable novel device applications. There has been a large interest on beyond graphene 2D materials, with particular emphasis on monoelemental materials (phosphorene, silicene, tellurene, etc.), 2D compounds (MXenes, oxides, nitrides, carbides and chalcogenides), their alloys and layered van der Waals heterostructures. This is not only signified from the significant increase in the number of peer reviewed publications each year in this area of research, but also from the number of abstract submissions to symposium Beyond Graphene 2D Materials Synthesis, Properties and Device Applications at the Materials Research Society (MRS) Fall 2019 meeting. This Perspective article highlights some of the recent advances in the field from a diverse international community of theoretical and experimental researchers who participated in this symposium in four prominent areas: Synthesis, Characterization, Properties, and Devices.
