Compared to chemically derived graphene (Gr), chemical deposition (CVD) grown Gr has better crystal quality and hence superior electrical properties, which render it applicable for next-generation electronic and applications including solar cells, , , sensors, etc. Though the excellent performance of CVD grown Gr based devices has been demonstrated on the lab scale, Industrial scale production of these devices is limited by reliable large-scale production and transfer of CVD grown Gr. In this review, we will summarize the latest developments on large scale CVD production of Gr and industrially applicable transfer methods.
Two-dimensional (2D) materials offer several unique advantages for high-performance light detection including fast response, high responsivity, broadband response and relatively low noise levels. 2D materials integrated photodetectors often use chemical vapor deposition grown materials, which despite their good quality are relatively high cost and not easily scalable. 2D materials based inks, fabricated through liquid phase exfoliation of bulk crystals, are attractive alternatives due to their low cost, ease of processing and scalable production. Combined with these advantages, mature printing methods available for 2D inks allow large scale electronic device fabrication for a variety of high performance applications including energy storage, solar cells, photodetectors, etc. In this review, we summarize production of 2D materials based inks, their printing methods, and applications for high performance photodetection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
