Electron momentum densities near Dirac cones: Anisotropic Umklapp scattering and momentum broadening
Abstract The relationship between electron momentum densities (EMDs) and a band gap is clarified in momentum space. The interference between wavefunctions via reciprocal lattice vectors, making a band gap in momentum space, causes the scattering of electrons from the first Brillouin zone to the othe...
