title: Strongly enhanced Raman scattering of Cu-phthalocyanine sandwiched between graphene and Au(111).
abstract: Graphene and flat gold have both been argued to enhance Raman scattering of molecular adsorbates through a chemical mechanism. Here we show that these two effects can add to each other. For Cu-phthalocyanine in between graphene and Au(111) on mica a Raman enhancement up to 68-fold has been observed.
