ok well we know that conductance is measured by the ability of an electron to jump to the conduction band from the valence band...poisonives said:wwell... actually not so sure anymore.. can u tell me ur reasoning for d?
therefore, it makes sense that electrons travel through conduction bands, as electrons (or holes) in the valence band of an insulator must go to the conduction band to travel to another atom, coz if they could travel in valence bands, this contradicts the notion that insulators are non-conductive as electrons cant jump to the conduction band.
