Abstract
:
The atomic and electronic structures of graphane (hydrogen-passivated graphene) are theoretically investigated using the local density approximation (LDA) of the density functional theory (DFT) and the pseudopotential method. Our total energy calculations suggest that the chairlike configuration for graphane is more energetically stable than the boatlike and tablelike configurations by approximately 0.129 eV/cell and 0.655 eV/cell, respectively. Our calculations suggest that the LDA band gap of the chairlike structure is approximately 3.9 eV. The equilibrium geometry and the band structure of the chairlike conformer are investigated and compared with the available experimental and theoretical data. We further present total and partial charge density to reveal the orbital nature of the highest occupied and the lowest unoccupied states.
