Abstract Novel systems of layered graphene are attracting interest for theories and applications. The stability, band structures of few-layer graphite films, and their dependence on electric field applied along the c -axis are examined within the density functional theory. We predict that those of Bernal type and also rhombohedral type tri- and tetra-layer graphite films exhibit stability. Rhombohedral-type systems, including AB-bilayer, show variable band gap induced by perpendicular electric fields, whereas the other systems, such as the Bernal-type films, stay semi-metallic.

Nobel Lecture: Graphene: Materials in the Flatland (2011, background): “…consider Bernal stacking versus rhombohedral versus hexagonal versus turbostratic, and, in bilayer, a small rotation between the individual layers leads to the appearance of van Hove singularities at low energies (Aoki and Amawashi, 2007; dos Santos et al., 2007; Li et al., 2010; Mak et al., 2010).”
