Single-step growth of graphene and graphene-based

2.1.1. PECVD growth of graphene sheets on transition metal substrates. Generally speaking, graphene growth could be achieved at a reduced temperature by PECVD on different transition metal substrates such as Co [18, 19],Ni[20–23], and Cu [11, 24–31]. Among the pioneering works, Woo et al grew high-quality and uniform graphene films at 850°Cina remote RF-PECVD system [20].

Basic PECVD Plasma Processes (SiH based)

Refractive index – why is it important in PECVD? Refractive index is a good indicator of film composition, i.e. Si:N ratio or Si:O ratio. (If Si content is high, the refractive index will be high) It can be easily measured by ellipsometer or prism coupler, allowing rapid evaluation of film composition (and unifomrity of composition).
