Effective masses along two directions are highly anisotropic for a isotropic 2D sheet of GaS. Also the fractional coordinates are not zero for other axis.

@ashima29R Did you ever resolve this issue? We are having similar problems with MoS2, where it appears that one of the two in plane-effective masses is swapped for the out-of-plane...

Effective masses along two directions are highly anisotropic for a isotropic 2D sheet of GaS. Also the fractional coordinates are not zero for other axis.

For the electrons at the T point (direction) of MoS2 we expect: - effective mass in-plane1 == effective mass in-plane2 (in-plane -> with k vector in xy plane) - A...
