제목 Xenon Flash lamp-Induced Multilayer Graphene Synthesis
초록  Graphene, the two-dimensional (2D) carbon materials, has great potential for various applications such as transparent electrode, high speed semiconductor, flexible display and sensor owing to its outstanding electrical, mechanical, thermal, chemical and optical properties. To apply these remarkable properties of graphene to real-consumer electronic devices, many researchers have made a great efforts to find graphene synthesis method that satisfy both fast growth rate and large scale growth. Hong et al. succeeded the large-scale graphene synthesis by using chemical vapor deposition (CVD) method in 2009, however, this technique has limitation to mass production of graphene because it takes a few hours to proceed heat treatment including heating and cooling process.
In this study, we demonstrated a new synthesis method for high fast fabrication of graphene by flash lamp-induced heat treatment. Due to the light duration of our xenon flash lamp is 3 or 15ms, all thermal process containing heating, synthesis and cooling to room temperature will take place within 3 or 15ms. This process is more 4 orders of magnitude faster than conventional CVD method. Flash lamp-induced graphene synthesis method would not only be one of the best ways to mass-production of graphene, but also facilitate graphene-based device applications.
