In this study, the graphene layers were transferred layer-by-layer onto the surfaces of LiNbO3 crystals at room temperature under atmospheric conditions. The graphene layers have an incommensurately stacked structure and there is no crystalline correlation between the layers. In order to confirm … Zobraziť viac Intra-layer lattice deformation is a strain state in which phonons do not leak to the neighboring graphene layers. The magnitude of this deformation is … Zobraziť viac Inter-layer lattice deformation refers to a strain state in which phonons can leak into neighboring graphene layers. Information about inter-layer lattice … Zobraziť viac The above results confirm that, in addition to van der Waals interactions, phonon interactions occur between graphene layers in few-layer graphene with odd layer … Zobraziť viac Because the graphene/LiNbO3 structures are formed by transferring graphene layers to the LiNbO3 substrate, there is no thermal stress at the interface at the … Zobraziť viac Web3. mar 2015 · Graphene flakes were mechanically exfoliated from natural graphite onto an ~1-μm-thick LOR layer covering the highly doped Si/SiO 2 substrate (acting as a back … china ozone factory
