ABSTRACT: Opening a band gap in bilayer graphene (BLG) is of significance for potential applications in graphene-based electronic and photonic devices. Here, we report the Tellurium intercalation in epitaxial graphene on Ir (111) enables the emergence of a spin–orbit-induced bandgap with energy spin splitting. By combining STM, ARPES, spin This, for example, prevents the use of graphene in making transistors. Although several proposals have been made to open a gap in graphene€s electronic spectra, they all require complex

Graphene was deposited on a transparent and flexible substrate, and tensile strain up to ∼0.8% was loaded by stretching the substrate in one direction. Raman spectra of Researchers have engineered a large energy band gap in a graphene layer grown on a silicon carbide substrate. The induced band gap in this periodic graphene system resembles the gap opening in graphene nanoribbons.19 However, the di fference between these two systems is that in graphene

Thereby, the vertical corrugation induced by the interface results in strain within the graphene lattice, which further amplifies this charge density wave ground state. Deformation-dependent bandgap diagrams are constructed over a wide range of the strain tensor parameters of up to 26%, which is close to predicted graphene breaking point.

This, in turn, results in a considerable bandgap in Graphene. Subsequently, magnetic spin effect might be used to tailor such bandgap, according to the requirement of the
