$addefmassxyz

$addefmassxyz is the command to input effective mass along different directions and considering the valley number. The format is Z is the growth direction.

$addefmassxyz
type  mhh_z  mhh_x  mhh_y N_valley $\Delta E_{hh}$  mlh_z  mlh_x  mlh_y N_valley $\Delta E_{lh}$  me_z  me_x  me_y N_valley $\Delta E_{c}$ me2_z  me2_x  me2_y N_valley  $\Delta E_{c2}$

If type = 1, the 2nd electron valley is not considered. For example, For Si in the bulk condition with 6 valleys

If type = 2, the 2nd electron valley is not considered. For GaAs material with 2nd valley has 3 valley in the X valley above gamma by 0.35eV
