Inside a system of DFT made on maximum capacity goals on the Electronic structure, electronic charge thickness, Fermi surface and optical properties we will play out a top to bottom examination of Ca4Bi6O13 compound. With DOS the investigated compound have metallic nature at a Fermi vitality equivalent to 16.4, 16.27 and 14.89 states/eV, and the straightforward direct lowtemperature electronic explicit warmth coefficient (?) for EVGGA, GGA and LDA is start to be 2.84, 2.82 and 2.58 mJ/mol-K2 correspondingly. The fanciful and genuine pieces of the dielectric work were expected by optical scattering. We feature that in the fanciful and genuine pieces of the recurrence subordinate dielectric work the sharp ascent at low energies (underneath 1.0 eV). We can gather the outcomes as: it is appeared by the electronic structure counts that valence band most extreme and the conduction band least happens at ?-point, bringing about an immediate vitality band hole. The conduction band in the higher vitality state comprises of Ca 3d states and the conduction band in the lower vitality locale is essentially made with the admixture of Bi 6p and O 2p.The thickness of states uncover that the conduction groups are generally made out of Cr-d states, though the valence groups are fundamentally overwhelmed by Cr-d, N-p and O-p states. The incomplete thickness of positions shows that there is a solid hybridization between O-p and N-s, Cr-d and C-p and furthermore between N-p and C-p states. The electronic charge thickness investigation shows that there is solid covalent bonds between Cr-d N-p, O-p and Cr-p, N-p and C-p and furthermore between Cr-d and O-p iotas. The TE (thermo-electric) study suggests that this material has potential in thermoelectric side.
