Berry curvature and energy bands of graphene

In this paper energy bands and Berry curvature of graphene was studied. Desired Hamiltonian regarding the next-nearest neighbors obtained by tight binding model. By using the second quantization approach, the transformation matrix is calculated and the Hamiltonian of system is diagonalized. With this Hamiltonian, the band structure and wave function can be calculated. By using calculated wave f...

Electronic energy bands and optical properties of ScH ,

Electronic energy bands of ScH, in the fluorite structure have been calculated by the composite-wave variational version of the APW method. The crystal potential was constructed by superposition of the atomic potential of Herman and Skillman. From the band structure data the density of states (DOS), the joint DOS (JDOS) and the Fermi surface have been worked out. The results of the JDOS calcula...
