The discovery of graphene has led to the devotion intensive efforts, theoretical and experimental, produce two-dimensional (2D) materials that can be used for developing functional devices. This work provides a brief review recent developments in lattice models 2D Dirac their relevant real material counterparts are crucial understanding origins cones electronic band structures as well design device applications. We focus on roles symmetry, atomic orbital hybridization, spin–orbit coupling presence cone. A number models, such honeycomb, kagome, ruby, star, Cairo, line-centered with different symmetries reviewed based tight-binding approach. Inorganic organic materials, theoretically proposed or experimentally synthesized satisfy these summarized.
