ehim ehim...hello,

I wonder if anyone knows about “group theory” [= approximation method] which is helpful in describing band gap structure of semiconductor oxides, my main problem is the high symmetry points i.e. gama point which occur at k=0 [the first Brillion zone], how it varies from gama 1 to gama 7 when the bands splits -under the effect of crystal field and spin-orbit splitting- and what do these numbers represent, if anyone have a brief explanation of it please do. also any articles, books or sites that you recommend will be helpful. thanks.
