I would like to ask about the reason why the electron "effective mass" was introduced in semiconductors. What is its' usefulness ?
And also about the so-called "effective mass theory" used to calculate energies for the shallow defects in semiconducors. What are mean pecularities and approximations of this theory and why we can't use it to calculate deep defects.
Thanks.
