Projection operator approach to unfolding supercell band structures
M. Farjam
While the methodology of band structure unfolding has appeared in several publications, the original derivations of the unfolding formulas can be considerably simplified by using t…
Visualizing influence of point defects on electronic band structure of graphene
M. Farjam
The supercell approach enables us to treat the electronic structure of defective crystals, but the calculated energy bands are too complicated to understand or to compare with angl…
First-principles study of bandgap effects in graphene due to hydrogen adsorption
Mahboobeh Mirzadeh, Mani Farjam
Hydrogen adsorption on graphene in commensurate periodic arrangements leads to bandgap opening at the Dirac point and the emergence of dispersionless midgap bands. We study these b…
Effect of hydrogen adsorption on the quasiparticle spectra of graphene
M. Farjam, D. Haberer, A. Grüneis
We use the non-interacting tight-binding model to study the effect of isolated hydrogen adsorbates on the quasiparticle spectra of single-layer graphene. Using the Green's function…
Uniaxial strain on gapped graphene
M. Farjam, H. Rafii-Tabar
We study the effect of uniaxial strain on the electronic band structure of gapped graphene. We consider two types of gapped graphene, one which breaks the symmetry between the two…
Comment on "Band structure engineering of graphene by strain: First-principles calculations"
M. Farjam, H. Rafii-Tabar
In their first-principles calculations of the electronic band structure of graphene under uniaxial strain, Gui, Li, and Zhong [Phys. Rev. B \textbf{78}, 075435 (2008)] have found o…
