WebOct 5, 2010 · Graphene – the perfect atomic lattice. A thin flake of ordinary carbon, just one atom thick, lies behind this year’s Nobel Prize in Physics. Andre Geim and Konstantin Novoselov have shown that carbon in such a flat form has exceptional properties that originate from the remarkable world of quantum physics. Graphene is a form of carbon. WebJul 15, 2024 · My problem is that I need to apply TBA to Graphene. I went through the article that is attached below, got the 2nd quantization hamiltonian eigenvalues and eigenvectors, did taylor expansion around K and K', got Fermi velocity and K and K' points positions. But for further calculations I need wave functions of pi and pi* orbitals.
