High-energy band structure of gold

On Parallel Calculation of Energy Band Structure

Abst rac t : We propose a parallel method for calculating the energy band structure. Our method can be easily implemented and does not require high speed of communication between the processors. In practical application our method allows for linear increase of the speed of calculations with the number of processors. We also analyse the optimization algorithms for energy band structure. We concl...

Electronic band structure of a Carbon nanotube superlattice

By employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (CNT) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. Exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. The calculations are base...

The low energy electronic band structure of bilayer graphene

We employ the tight binding model to describe the electronic band structure of bilayer graphene and we explain how the optical absorption coefficient of a bilayer is influenced by the presence and dispersion of the electronic bands, in contrast to the featureless absorption coefficient of monolayer graphene. We show that the effective low energy Hamiltonian is dominated by chiral quasiparticles...
