Lecture 5 : Graphene : Electronic band structure and Dirac fermions
A suspended sheet of pure graphene – a plane layer of C atoms bonded together in a honeycomb lattice – is the “most two-dimensional” system imaginable. Such sheets have long been known to exist in disguised forms – in graphite (many graphene sheets stacked on top of one another), C nanotubes (a graphene sheet rolled into a cylinder) and fullerenes (buckyballs), which are small areas of a graphe...
متن کاملHubbard-U band-structure methods.
The last decade has seen a large increase in the number of electronic-structure calculations that involve adding a Hubbard term to the local-density approximation band-structure Hamiltonian. The Hubbard term is then determined either at the mean-field level or with sophisticated many-body techniques such as using dynamical mean-field theory. We review the physics underlying these approaches and...
متن کاملElectronic 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...

متن کاملElectronic properties of the three - band Hubbard model
We study the electronic band-structure and transport properties of a CuO2-plane within the three-band Hubbard model. The Dynamical Mean-Field Theory (DMFT) is used to solve the many particle problem. The calculations show that the optical gap ∆opt is given by excitations from the lower Hubbard band into the so called Zhang-Rice singlet band. The optical gap ∆opt turns out to be considerably sma...
