Abstract
The authors investigated the influence of substrates on Raman scattering spectrum from graphene. The room-temperature Raman signatures from graphene layers on GaAs, sapphire, and glass substrates were compared with those from graphene on the standard Si∕SiO2 (300nm) substrate, which served as a reference. It was found that while G peak of graphene on Si∕SiO2 and GaAs is positioned at 1580cm−1, it is downshifted by ∼5cm−1 for graphene on sapphire and, in some cases, splits into doublets for graphene on glass with the central frequency around 1580cm−1. The obtained results are important for nanometrology of graphene and graphene-based devices.Keywords
