First I did the DFT calculations (scf) on a dense k-grid and calculated the transport properties using BoltzTrap code. </div><div><b>Note: </b>I am using VASP as a DFT code.</div><div>I want to compare the Boltawann results with the BoltzTrap calculated results. I got the nice Wannier fitting on the DFTbands. But there is a huge difference in the value of the Seebeck coefficient approximately 4.5 times. What could be the reason for this?
