| DOS at the Fermi level means how many states can be conductivities at the Fermi level. It is strongly correlated to its transport properties measured in experiment. If your DOS is 2-3 times of that in literature, one of the two or even both of the two are wrong. Check your DOS calculations (especially kpoints), and print more DOS points in your calculations. Test your smearing method. Lastly, make sure again you are comparing the exactly same DOS as the literature. |
