This Good Practice Guide has been written by the National Physical Laboratory (NPL) in collaboration with the National Graphene Institute (NGI), at the University of Manchester.
The guide will enable you to find out:
guidance on characterising the structural properties of graphene, so that the graphene community can adopt a common, metrological approach that allows the comparison of real-world graphene samples
guidelines on how to initially assess the measurements required depending on the type of sample in different forms, that is, either a graphene sheet on a substrate, or graphene flakes present in a powder or liquid dispersion, and includes decision trees and flow diagrams
how to detail the accurate determination of the graphene coverage of a substrate, the number of layers/thickness, the lateral dimensions of flakes, layer alignment and the level of disorder
how to cover sample preparation, measurement issues, sources of uncertainty and how to analyse data
