SUMMARY
Break points in band structure refer to the intersections of energy bands in the εnk vs. k plot, where ε represents energy and k represents the wave vector. When two bands intersect, the lower energy band is indexed as band 1 and the higher energy band as band 2, leading to discontinuities in the energy surface, particularly in Dirac cone structures. This phenomenon indicates critical points in the electronic properties of materials, as described in Jenö Sólyom and A. Piróth's "Fundamentals of the Physics of Solids Volume II".
