| Outline of Final Research Achievements |
At the phase transition of topological insulators in three dimensions, the band gap closes and Dirac/Weyl semimetal phases are realized. These topological semimetals are robust against randomness, but eventually undergo diffusive metal transition. The critical behavior of this semimetal-diffusive metal transition is described by the density of state scaling.
In this study, we have demonstrated that the scaling of the density of states is valid in many situations. In addition, scaling behaviors of conductance/group velocity is discussed.
