    Research output: Contribution to journalArticlepeer-review


    The use of vibrational sum-frequency spectroscopy (VSFS) to study transferred graphene, produced by
    chemical vapour deposition, is presented. The VSF spectrum shows a clear C-H stretching mode at
    ~2924 cm-1, which is attributed to residue of the polymer used for the transfer. This makes VSFS a
    powerful tool to identify adsorbates and contaminants affecting the properties of graphene.
