Fig. 8From: Simultaneous synthesis of nanodiamonds and graphene via plasma enhanced chemical vapor deposition (MW PE-CVD) on copperArea density and size analysis of nanodiamond spheres. Results of analysis for the sphere size and the sphere area density for increasing methane concentrations (left) and the graphical result for sphere size (middle) and the sphere’s area density (right) as a function of the C2/Hα-ratio. An increasing C2/Hα-ratio leads to taller nanodiamond spheres whereas the C2/Hα-ratio is inversely proportional to the number of spheres per unit areaBack to article page
