A review of large-area bilayer graphene synthesis by chemical vapor deposition
Bilayer graphene has attracted considerable attention due to its potential as a tunable band gap in AB-stacked bilayers. Recently, great advancements have been made in the synthesis of chemical-vapor-deposited bilayer graphene. This featured article provides a detailed and up-to-date review of the synthesis of bilayer graphene by chemical vapor deposition (CVD). We will discuss various approaches to synthesize bilayer graphene and the corresponding growth dynamics. Methods for identifying the growth mechanism of bilayer graphene on Cu enclosures are highlighted for a deeper understanding of better control over uniformity and thickness.
