Fermi level for an intrinsic semiconductor lies midway between the valence and conduction bands, bcoz---a) the temperature does not influence its position.b) the effective mass of hole is greater than that of electronc) the effective mass of electron is taken equal to that of holed) none of the abovewhich is the right option?
