gngguTypewritten TextThe bond picture is important if you work with not so conventionalsemiconductors: a-Si, sp2 carbon based stuff etc.

gngguTypewritten Text* The band gap is the consequence of Bragg diffraction of e waves.

gngguTypewritten TextTo better understand the stuff, read Kittel, Intro to Solid State Phys, the chapter on band theory.
