We compute the thermodynamic properties and density of states of disordered kagome lattice doped with impurity atoms in the context of tight binding model Hamiltonian due to spin–orbit coupling. The effect of scattering by dilute charged impurities is discussed in terms of the self-consistent Born approximation. Green’s function approach has been implemented to find the behavior of density of states and thermodynamic properties of kagome lattice. Specially, temperature dependence of Pauli paramagnetic spin susceptibility and specific heat of kagome structure in the presence of impurity atoms has been analyzed. Also the effects of impurity concentration and scattering potential strength on behaviors of specific heat and paramagnetic susceptibility of kagome structure have been studied. Our numerical results show that specific heat reaches the Schottky anomaly peak. The height of this peak decreases with impurity concentration and scattering potential strength. The temperature dependence of paramagnetic susceptibility indicates a decreasing behavior at low temperatures. Additionally, throughout our study, we observed variations in the density of states curves, indicating the influenes of both impurity atoms and spin–orbit coupling.
