Hello,
I have read in several textbooks and articles of semiconductor physics that the valence bands are p-like state. So, even in the mathematical calculation in k.p theory, it is widely used, especially to define heavy holes and light holes states.
My question is: How acurate is this? Why do they say p-like and not p if this is exact? If I want to rotate such a state, can I simply use the rotation matrix for the l=1 angular momentum?
I am not very familiar with group theory unfortunately, but is there a way to answer this question by using the symmetry of the crystal? Let's say the zinc blende structure...
Thank you in advance for any help.
