In graphene, a Kekulé-Y bond texture modifies the electronic band structure, generating two concentric Dirac cones with different Fermi velocities lying in the Γ point in reciprocal space …

An overview of two-dimensional (2D) materials electronic properties is presented, including research in multilayered heterostructures. An emphasis is made on simple models that …
A Kubo formalism is used to calculate the electronic and optical conductivity of a graphene superlattice with Y-shaped Kekulé bond texture, similar to that visualized in recent …
The formation of a superlattice in graphene can serve as a way to modify its electronic band structure and thus to engineer its electronic transport properties. Recent experiments have …
Motivated by recent experimental findings on the low-energy spectrum of Kekulé-patterned graphene, the optoelectronic signatures of graphene superlattices with a spatial modulation …
We demonstrate that the current flow in graphene can be guided on atomically thin current pathways by the engineering of Kekulé-O distortions. A grain boundary in these distortions …
The electronic and optical conductivities for anisotropic tilted Dirac semimetals are calculated using the Kubo formula. It is shown that, as in graphene, the minimal conductivity …
We theoretically study the Josephson effect in a superconductor/normal metal/superconductor junction based on Kekulé patterned graphene. For the Kekulé-O …
The effects of second-neighbor interactions in Kekulé-Y patterned graphene electronic properties are studied starting from a tight-binding Hamiltonian. Thereafter, a low-energy …
