May 6 at 15:11 comment added freecharly In a material with a conduction and valence band the usual equations for carrier densities still hold, but in large bandgap materials the electron and hole densities become so low and thus insignificant, that other conduction mechanisms, like, e.g, ionic conduction in quartz, become dominant.
May 6 at 14:41 comment added freecharly That "as the bandgap increases, the material becomes more and more ionic," is in general, not the case. Look at the large bandgap of diamond compared to silicon , which is not at all ionic and has pure covalent bonds!
