Nanotechnologies — Structural characterization of graphene — Part 2: Graphene sheets on a substrate

Scope

This document details the methods for characterising the structural properties of CVD-grown graphene. The methods used are optical microscopy, Raman spectroscopy and transmission electron microscopy (TEM). The properties determined are the percentage of substrate coverage of graphene, number of layers, the level of disorder and layer stacking. Sample preparation routines, measurement protocols and data analysis for the characterisation of CVD-grown graphene are provided.
