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 .
May 14, 2018 · Herein, we devise an in situ encapsulation strategy to directly grow ultrathin graphene shells over T‐Nb2O5 nanowires (denoted as Gr‐Nb2O5 composites) via plasma‐enhanced chemical vapor deposition (PECVD) as the durable anode materials for Na‐HSC devices.
for the synthesis of graphene, the resulting carbon structures often lack of quality being FLG with considerable amount of defects.11,12 The high defect density in PECVD graphene is referred to energetic particles from the plasma interacting with the growing surface. Nevertheless there have
Graphene directly grown on dielectric substrates by chemical vapor deposition (CVD) or plasma-enhanced CVD (PECVD) usually suffers from poor crystalline quality and sometimes coexisting amorphous carbon.
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).
Distinguished from other kinds of 3D graphene structures, the well‐developed, vertically aligned graphene nanosheet arrays (VAGNAs) could be grown on a variety of substrates by plasma‐enhanced chemical vapor deposition (PECVD), forming a 3D interconnected structure with intimate contact with substrates and largely exposed edges, and easily accessible open surfaces of the graphene nanosheets.

Carbon is a ubiquitous material that has been ever found whereas the epoch making material graphene is also an allotropy of carbon. Actually graphene is a two-dimen- sional, single-layer sheet of sp2 hybridized carbon atoms and has arrested enormous attention and research motives for its versatile properties.
