Abstract
We report the calculation of the Density of States (DOS) in Twisted Bilayer Graphene (TBG) system for low energy range near Fermi level using commensurate rotation of 1.160, 1.790 and 3.480. We obtain a logarithmic behaviour of DOS showing that van Hove Singularities (VHS) are occurred in this system and its position depends on twisted angle. This behaviour coming from the saddle points (SP) of band dispersion of TBG. The position of VHS will move away from Fermi level along with the increase of twisted angle. This result can be used to calculate others physical quantities such as optical conductivity or critical temperature of superconductivity that may occur in TBG.
