However, in semiconductors the bands are near enough to the fermi level to be thermally populated with electrons or holes. As the temperature is increased, electrons start to exist in higher energy states too. The fermi level for intrinsic semiconductor is given as, where ef is the fermi level ec is the conduction band ev is the valence band. A semiconductor material has an electrical conductivity value falling between that of a conductor, such as metallic copper, and an insulator, such as glass. In semiconductors, the fermi energy is between the valence and conduction band, but the band gap is smaller, allowing electrons to jump the gap fairly easily, given the energy to do it.
The fermi level does not only lie in the center of the bandgap, it can be shifted up and down the fundamentals of solid state physics can be found even at the wikipedia (see the answer by gazi in intrinsic semiconductors, the fermi energy level lies exactly between valence band and conduction.
