The influence of ripple waves on the band diagram of zigzag strained graphene nanoribbons (GNRs) is analyzed by utilizing the finite element method. Such waves have their origin in electromechanical effects. With a novel model, we demonstrate that electron-hole band diagrams of GNRs are highly ...
An 'Energy Band Diagram' is a graphical representation in semiconductor physics that illustrates the allowed and disallowed bands of energy in a crystal lattice. It shows the energy levels of electrons in the valence band and conduction band, determining the conductivity properties of the material. ...

Bernal bilayer graphene (BLG) offers a highly flexible platform for tuning the band structure, featuring two distinct regimes. One is a tunable band gap induced by large displacement fields. Another is a gapless metallic band occurring at low fields, featuring rich fine structure consisting of four...
We analyze the phase diagram of twisted graphene bilayers near a magic angle. We consider the effect of the long range Coulomb interaction, treated within the self consistent Hartree-Fock approximation, and we study arbitrary band fillings. We find a rich phase diagram, with different broken symme...

Figure 1a shows a diagram of the proposed graphene absorber, which comprises compound grating (top grating), monolayer graphene, SiO2 spacer layer, and ZCG (bottom grating). Monolayer graphene was sandwiched between the top grating and the SiO2 spacer layer. The bottom grating was deposited on ...
3a), because of the energy splitting in spin or pseudospin (or valley) degree of freedom. This half-integer QHE has been indirectly observed in graphene (where with a fourfold degeneracy, a (4n+2)e2/h Hall conductance has been observed), which is a prototype Dirac system [93,94]. In ...
Band structure of graphene around theFermi levelcan be determined by the pzorbital. The pzelectrons of graphene are responsible for the π-band. The presence of two atoms gives rise to two π-band called as π and π*. The cone-likeconduction bandfor theπ∗ electrons (at higher energy...
