<p>The hole effective mass has a slightly different equation [

substantially more complex [

I am calculating effective mass of electron using the procedure
as provided in <a

and I calculate electron effective mass. But when i follow the
same procedure to calculate the hole effective mass the
difference is very large with the references.

Is there any different procedure other then electron effective
