Bulk Si eff. mass vs. biaxial Strain
I was simulating Strain sweep on Bulk Si. I applied biaxial strain from -0.015 to 0.015 in 001 direction. I am interested in hole effective mass change as a function of strain. For the HH effmass vs. strain data, the eff mass for strain=0 is 1/2 of the bulk case (0.049m0) as given in literature. Can anyone tell me if I am doing anything wrong? I expect to see bulk HH and LH mass for strain=0 and I am not getting that for any direction. Please help.
