Industrial Production of Graphene Materials for Consumer Electronics and Quantum Technology

Large-scale production of graphene by continuous roll-to-roll chemical vapor deposition (R2RCVD) was proposed 14 years ago, but its realization was limited due to the lack of killer applications to pioneer the global market. Recently, as electrothermal heating and heat dissipation applications based on graphene materials have received great attention in the consumer electronics sector, global consumer electronics companies have made large investments to install commercial production facilities in Korea and develop related industrial processes. In addition, graphene-based sensors and quantum devices are being developed on a graphene-on-silicon wafer platform. In this lecture, we will reveiw the recent progress on R2RCVD production of graphene films and AI-assisted quality assessment methods, which are essential for high-throughput cost-effective synthesis. We will also discuss the characteristic mid-IR radiation, electrothermal plasmon extraction, and interlayer stacking-order changes of graphene, and their applications to cooking and heating appliances, ultra-sensitive point-of-care biochemical sensors, quantum sensor devices, etc.
