I'm studying quantum mechanics and I want to understand perfectly where the bands of the electronic sturcture come from. I've read that it is related with the periodic potential, Bloch waves and Kronig–Penney model but, honestly, I didn't understand it very well.
Can you recommend me some book that explains this topic, using all the topics I wrote above, in a more intuitive way rather than in a purely mathematical one? (Although a not too complex mathematical justification would be great, too).
I like Ashcroft and Mermin, Kittel, Mardar, and Landau and Lifschitz .
