Figure 4From: Graphitic carbon grown on fluorides by molecular beam epitaxyAFM images of graphitic carbon on MgF 2 . AFM images of 1 × 1 μm (a) before and (b) after the graphitic carbon growth on MgF2. The mean roughness parameters, Ra, from 1 × 1 μm scans are (a) 0.97 and (b) 2.45 nm, respectively.Back to article page
