Graphene and related two-dimensional materials such as MoS₂ and WSe₂ emerged about 2 decades ago as promising candidates for electronic, photonic, and sensing applications. Potential uses span continued downscaling of logic devices (in line with Moore’s law), high-frequency electronic circuits, ultrafast optoelectronics for optical communications, and flexible electronics. In this talk, I will provide an overview of progress in these areas, with a focus on recent results involving photodetectors, THz-detectors, and graphene-based integrated circuits for flexible electronic applications. 

A key requirement for the commercial success of these technologies is largevolume, wafer-scale manufacturing. Although wafer-scale growth of graphene and other 2D materials has been demonstrated using chemical vapor deposition and related techniques, the yield and reproducibility of fabricated devices remain below what is needed for practical deployment. I will summarize the current state of wafer-scale production and highlight the major challenges that must be addressed.
