Dear experts,

I have calculated the FatBS and PDOS for twisted bilayer MoS2. The unit cell contains 1302 atoms. I used dftb calculation and got the PDOS in the energy window of [-2.5:+2.5] with 601 points (energy resolution 8.3 meV). I also used tetrahedron method. As you can see in the attachment, there exist a Dirac nod in the valence bands. I expect to have a tiny channel in the PDOS, but I observed a gap with respect to Dirac energy window. The data is also available in the attached figure, where the left highlighted column is the energy and right is the total PDOS. To my knowledge, the two zero values in PDOS at -0.858 and -0.85 is not in agreement with the Dirac band in the left plot. Hence, I appreciate any comments/suggestion.

Cheers, A
