If fermi level is changing with temperature its ok. my quaestion was when temperature up energies of covalence band also up. so if highest energy electrons @ covalance band occupy near to fermilevel @ 0 K (fermi level is the upper ,argin of the fermi sea) when temperature up higest covelence...

In a semiconductor @ 0k highest energy state lie on fermilevel(all electrons @ valence band). but @ room temperature highest energy state of covelence band lie below the fermilevel. how can i understand this? pls help me.
