Vibrational fingerprints of residual polymer on transferred CVD-graphene

Research output: Contribution to journalArticle

Abstract

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.
