https://www.physicsforums.com/th ... dirac-point.537928/ Hence, the electrons and holes are called Dirac fermions, and the six corners of the Brillouin zone are called the Dirac points. Reference https://www.physicsforums.com/th ... dirac-point.537928/ https://www.quora.com/What-is-the-Dirac-point-in-graphene The conduction and valence bands meet each other in graphene, which is like a zero band gap semiconductor. The six points in the two dimensional Brillouin zone where the bands meet are called Dirac points. They are called Dirac points since the linearity of the dispersion relation near these points means that the charge carriers satisfy an equation of motion that has the same form as the (relativistic) zero mass Dirac equation. https://www.researchgate.net/pos ... _in_a_simple_manner The Dirac point is the crossing point of the linear energy dispersion curves E_+(k)=+ v_F.k, E_-(k) =-v_F.k . https://arxiv.org/pdf/1004.3396.pdf The Fermi level is, therefore, situated at the points, called Dirac points, where the π band touches the π band. |
