Dear Ashkan,
using the k-path selection tool of XCrysDen I get the coordinates:
0.000000 0.000000 0.000000 Gamma
0.500000 0.000000 0.000000 M
0.666666 -0.333333 0.000000 K
0.000000 0.000000 0.000000 Gamma
so a possible input for QE could be:
K_POINTS crystal_b
4
0.000000 0.000000 0.000000 50
0.500000 0.000000 0.000000 37
0.666666 -0.333333 0.000000 75
0.000000 0.000000 0.000000 1
Regards
Thomas

Dear Thomas,
Could you please tell me what is the true kpoint list on the path
gamma K M gamma?
I mean the coordinates of the points gamma, K, and M inn BZ.

Dear Ashkan,
Have you checked that you use the right k-point list in the band
structure calculation?
The K point seems to be wrong... The input file for the scf
calculation seems to be
correct even if you could probably use a smaller cutoff, which you
however need to check.
Regards
Thomas
P.S.: Please add your affiliation.

Dear all,
I was trying to calculate the band structure of monolayer MoS2
according to the input file below. Although the resulted band
structure had a band gap of about 1.9 eV, it didn't illustrate a
direct type band gap at K high symmetry point in Brillouin zone.
I was wondering if something is wrong with the input file?
