Meter sized single crystal graphine
WebHere, we demonstrate a rapid growth of graphitic nitrogen cluster–doped monolayer graphene single crystals on Cu foil with remarkable carrier mobility of 13,000 cm 2 V −1 s −1 and a greatly reduced sheet resistance of only 130 ohms square −1. Web9 feb. 2024 · Here, we describe an assisted self-assembly of twisted layer graphene. The process, which can be implemented in standard chemical vapour deposition (CVD) growth, is best described using the analogy to Origami and Kirigami of paper and involves wrinkle formation, folding, tearing, and re-growth.
