I have done band structure calculation (space group- P-6m2 ) and my Conduction Band Minimum donot lie in the high symmetry point. I could obtain two effective mass using sumo package. But to determine the mobility along arm chair and zigzag direction we need effective mass along those direction. If some one can assist me how to detemine effective mass along zigzag and armchair direction which is used in mobility calculation. I have attached the screenshot of formula to determine the mobility (DOI-Article A comprehensive study in carrier mobility and artificial pho...

.)

If there are any suggestion to determine the mobility by other methods It will also help me.

Thank you,
